Yes, but this time I concentrated on Drax instead of the much smaller Lynemouth. Drax is the largest power station in the UK - nearly 4 GW. At the moment, 2.6GW is biomass, and 1.3 GW coal. The government has imposed a deadline of 2025 after which, no UK power station will be allowed to burn coal. Drax expects to comfortably beat that deadline, and by switching over entirely to "renewable" fuel will soon be emitting more Carbon Dioxide than ever before, while still meeting (and getting government grants for meeting) renewable energy targets.

Re: Wind Turbines

More than they would using coal at the same output level, or exceeding it because of higher output?

Another question I have is if the CO2 levels are comparable to the alternative, are there other environmental benefits to the switch?

I consider, for example, how coal creates heavy metal pollution.

A massive wind turbine in New York City crashes down onto a car

(CNN)A recently installed wind turbine came crashing down in a New York City neighborhood, causing a chain reaction on Monday.
As the turbine in the Bronx partially collapsed, it smashed into an adjacent three-sided illuminated billboard, causing that also to break apart and come tumbling down to the street and cars below.
Pictures from the scene shot by Tori McCauseland with The Co-op City Times show a massive pole lying across a mangled car.

"Thankfully we can report that there are no injuries, and everyone is safe and sound," New York Mayor Bill de Blasio told CNN affiliate WABC. "An investigation into how this incident happened is underway."
The wind turbine, which is more than 150 feet tall, was installed in mid-December but had not yet been activated, according to WABC. Debris was strewn across the shopping center below that houses a gas station, pharmacy, paint store and other businesses. All the stores were evacuated, according to the New York City Department of Buildings (DOB).

Coal has a higher energy density than pellets but pellets can be burned more efficiently than coal. On average:

Energy content of coal: 24 MJ/kg @ 60%eff = 14.4 MJ/kg realized.
Energy content of pellets: 18 MJ/kg @ 80%eff = 14.4 MJ/kg realized.

So it's a wash.
Another question I have is if the CO2 levels are comparable to the alternative, are there other environmental benefits to the switch?

I consider, for example, how coal creates heavy metal pollution.
Coal is a nasty fuel. In modern plants, all those nasty heavy metals are scrubbed and stored as fly-ash. So while very little makes it to the air, it still has to be dealt with.

But that's where the benefit of wood pellets ends. It's hard to find an unbiased source that compares pellet CO2 emissions with other fuels because most of them only report 'surplus' or Life cycle CO2 rather than actual CO2.

I think volker-quaschning gives an unbiased picture.

https://www.volker-quaschning.de/datser ... ndex_e.php

But because the EU only considers life cycle, burning pellets gives those plants a free pass.

But not Too Free.

The cost comparison is an eye opener.

price of coal: $35.99/ton price of pellets:$250/ton

In the end, pellets are no panacea.

Re: Wind Turbines

When you compare the price per ton of pellets versus coal, you also have to consider energy density - you have to burn a greater weight of pellets than coal to produce the same amount of heat, so the pellet price is even higher than it first appears.

The actual density (weight per unit volume) of pellets is also much lower than that of coal, so you need more ships and rail cars to carry the fuel required. This was apparent when I worked at Lynemouth - the rail depot that used to handle the coal easily was stretched to breaking point and in need of expansion after the plant was converted to biomass. They also had to build extra silos to stockpile enough fuel to last between one shipment and the next - they like to stockpile at least a week's worth of fuel in case of supply problems, and a week's worth of pellets takes up a lot more room than a week's worth of coal.

There's also the energy input for producing the wood pellets to consider. The trees have to be felled, transported, cut up, and the pellets are then dried, compacted, etc. ready for transport. Much of the energy input to these processes comes from burning fossil fuels or from the electricity grid, but some estimates put the energy use of these processes equivalent to burning 10% to 20% of the wood in order to process the remaining 80% to 90%.

Of course, coal also has to be mined, broken up, washed and transported, but the energy inputs for those processes are generally much lower than for wood pellets. In the case of the UK, the power stations were often built directly over coal fields to minimize the transport costs, but now those same power stations are burning imported wood pellets, the cost of transport, both in energy and financial terms, is much greater.

The wood pellets also have health risks. The dust from the wood pellets is a known carcinogen, and special dust extractors, filters, and personal protective equipment are required at all stages of the transport and handling process.

The furnaces that raise the steam at Drax were designed for coal. Apparently the fumes caused by burning pellets contain extra acids or other chemicals that attack the steam tubes shortening their expected lifespan. One of the projects I was involved with at Drax, was to feed some sort of mineral powder additive into the furnaces that helped correct this problem. Of course, extra silos, monitoring and metering equipment was needed to store and feed the powder (I worked on the weighing equipment that measured and controlled the feed rate of the powder). The weight and volume of the powder was a tiny fraction compared to the pellets, but that powder still had to be bought, transported, stored, and monitored. I was never able to find out the actual composition of the powder - there seemed to be great secrecy concerning what it was. I don't know if that was for commercial or other reasons.

Kansas’ embrace of wind energy helps it reduce CO2 emissions

WICHITA, Kan. (AP) — Kansas has been able to reduce its carbon-dioxide emissions for a 10th straight year largely due to the rapid adoption of wind energy and a slow move away from coal powered electricity.

About 36% of all electricity produced in Kansas is from wind, the highest percentage of any U.S. state, the Kansas News Service reported. In 2019 alone, Kansas saw four new wind farms, adding enough capacity to power 190,000 homes for a year.

In 2017, about half of Kansas’ total carbon-dioxide emissions came from burning fossil fuels, such as coal and natural gas, to create electricity. Plant upgrades and federal environmental regulations since, have forced coal plants to clean up what was coming out of their smoke stacks.

Germany eyes new offshore wind farms dedicated to green hydrogen production

Move would be a world first in fast-moving sector — part of government plans to spend billions of euros to build up an industrial-scale domestic market for green H2

Germany is considering holding special offshore wind tenders to produce green hydrogen at an industrial scale, according to the draft of a national hydrogen strategy by the economics and energy ministry seen by Recharge.

Awarding areas at sea exclusively for hydrogen production is one out of 34 measures the ministry suggests in a 21-page draft document that will now undergo the scrutiny of other ministries before being presented by economics and energy minister Peter Altmaier.

“The designation of areas that can be used for the off-shore production of hydrogen, the necessary infrastructure and options for additional tenders for the generation of renewable energies will be relevant topics (implementation from 2020),” the draft stresses without giving more specific detail on when special tenders may be held or what volume they could have.

“Due to the high full load hours, wind energy at sea is an attractive technology for generating renewable electricity, which can be used for the production of CO2-free hydrogen,” it explains.

The proposal for a hydrogen strategy includes the need for billions of euros in support, and stresses that Germany will need to build up a strong domestic market for green hydrogen in order to become a world leader in hydrogen technology.

But it acknowledges that given the country’s limited own renewable energy generation capacities, it will also need to import large quantities of CO2-free hydrogen.

“The European Union, in particular with the North Sea, has geographically suitable and profitable locations for wind energy and thus offers great potential for the production of green hydrogen,” the proposal states, but also says that part of the hydrogen supply could come from non-EU nations, where renewables can be produced at very cheap prices on a large scale.

Re: Wind Turbines

Not only wind, but still a data point:
EU's CO2 emissions fall 12% in 2019 as wind and solar surpass coal

February 5 (Renewables Now) - The European Union’s (EU) electricity sector has emitted 12% less carbon dioxide (CO2) in 2019 compared to a year earlier as generation from hard coal- and lignite-fired power plants dropped by 24% on the year.

Greenhouse gas emissions went down by 120 million tonnes, which is the sharpest decline since at least 1990, shows a new study by Agora Energiewende and climate think-tank Sandbag.

“Last year’s decline in EU greenhouse gas emissions is thanks largely to the CO2 emissions price, which continued to drive climate-damaging energy sources from the market,” said Matthias Buck, the head of European energy policy at Agora Energiewende. He noted, though, that maintaining the price of CO2 emissions at current levels is crucial for ensuring the continued mitigation of global warming. In 2019, that price rose to about EUR 25 (USD 27.5) per tonne of CO2.

Buck also urged the EU Emissions Trading System to further lower the number of yearly permits it issues for greenhouse gas emissions in the energy, industrial and intra-European aviation sectors.

Last year saw the share of renewables in EU-wide power generation climb to a record high of 34.6%, or 1.8 percentage points higher than in 2018. The electricity produced by wind and solar parks rose by 64 TWh to 569 TWh in 2019 and thus, for the first time, surpassed the amount of coal-fired electricity by 100 TWh. Wind farms generated 14% more electricity in 2019 compared to 2018, while solar power plants experienced a 7% increase in their output. On the other hand, hydropower production went down by more than 6% because of ongoing drought.

When it comes to annual capacity additions, the study mentions that 16.8 GW of wind parks were installed across Europe in 2019, which is about 5.1 GW more than the year before. In the solar photovoltaic (PV) sector, annual additions doubled to 16.7 GW from 8.2 GW.

Buck, however, warns that the annual growth of renewable energy capacity should be accelerated if the EU is to achieve its 2030 target of having almost one-third of its total energy coming from renewables.

Britain sets new daily record for wind generation, topping 44% of country’s electricity consumption

Stormy conditions drove wind to a new record-high share of Britain’s electricity supply that at one point hit 56% this weekend, said power market analysts.

The record level, in the early hours of Saturday 8 February, beat a previous high of 52.4% set in September 2019, said analysis from Drax Electric Insights.

Saturday also set a new record for highest share of power produced in a single day with 44.26%, said Drax, outstripping both nuclear and gas combined.

The wind power records came amid the arrival of storm Ciara, which caused havoc to travel and infrastructure across the UK this weekend – and left thousands of consumers without any power at all.

The UK has 13.57GW of onshore wind installed, and a world-leading 8.4GW offshore fleet.

The two are currently on very different trajectories, with onshore installations plunging as a result of adverse government policies, while offshore is booming after being included as a key part of the national industrial strategy.

The wood pellets are officially classified as green, so the station now runs flat out 24/7 supplying base load, even at times of low demand when wind turbines are parked because their energy is not needed.

The tragedy is that the wood pellets are imported from North America's west coast. The carbon burned harvesting, processing, and transporting the fuel isn't taken into account when calculating the carbon footprint. Also there are big questions about the sustainability of cutting down mature trees and burning them to make electricity - no matter where in the world, and under what regulatory system those trees are felled.

The Czech company that owns and operates the power station doesn't care - targets are officially being met and the company is able to claim a £1m per day government subsidy for producing all that lovely "clean" energy.
Quincy Illinois until recently had a power plant that generated electricity by burning old tires. Finally local protests got it shut down.

You might think that even by greedy capitalist pig despoil the planet standards, it would be unprofitable to generate electricity that way.

However, they got a state subsidy because old tires were classified as "renewable". Remove the subsidy, close the plant.

There was probably some hanky-panky involved in getting the subsidy in the first place, but nobody pursued that.
If you just buried the tires, the carbon in them would be sequestered (as long as you don't accidentally cause a tire fire).

Re: Wind Turbines

That would only work for preventing the rise in atmospheric carbon dioxide if the fossil fuel burned by all the equipment and people that bury the tires contains less carbon than that contained in the actual tires.

I guess that would be the case providing you use an existing hole: stack the tires in worked-out existing mines. Make sure you don't burn much fossil fuel transporting and handling the tires though.

Re: Wind Turbines

Yes.

Tires are tricky things to recycle as they contain rubber, plastic, steel, and fibres all baked together. If they can't be recycled as tires, what are the options? Grind them up, bury them, stack them in huge piles on the surface, or burn them? All those approaches have drawbacks in energy use and pollution.

The French used to throw them in the ocean, claiming they would create useful habitats for fish and other marine life - but years later they had to admit that the tires were badly damaging the ocean, so they had to recover as many tires as possible back to land.

Re: Wind Turbines

I suppose that burning them isn't necessarily the worst option. If you get energy from it. But it's like burning a fossil fuel.

The French determined that throwing them in the ocean isn't a good idea.

If you could recycle them or reuse them somehow, that might be good, but I don't know how economic that really is.

If none of the above that leaves either burying them or making a mountain of discarded tires somewhere. Tire mountains often end up burning so that too seems bad:

I'll try to find the youtube video but it just so happens there's a new road construction process that uses whole tires with the sidewalls cut out as the foundation for roads highways. Here's how it works
1) cut surface the road, as usual.
2) instead of just spreading gravel as evenly for the foundation, first put down the tires, side by side, and fill them and the remaining spaces with number 8 gravel.
3) Pave over it with asphalt or concrete.

The constraint of the tire column eliminates compression and spreading. The loose aggregate elements freeze/thaw heaving.

Britain's power system is decarbonising faster than anywhere in the world, report finds

Britain's power system has been decarbonising at a faster rate than anywhere else in the world over the last decade, a new report has found.

Carbon emissions from the power sector have fallen by around two thirds over the last ten years, from 161 million tonnes in 2010 to 54 million metric tonnes in 2019.

It comes as the country's generators transition away from coal and natural gas to renewable energy sources, such as sustainable biomass.

In the electricity sector, a decrease in demand for power proved to be the biggest driver of the decline in emissions, according to the report by academics from Imperial College London for Drax Electric Insights.

Demand fell by 13 per cent, even as the population grew by seven per cent and GDP rose by a quarter, as measures such as more energy efficient lighting, manufacturing and other efficiency measures took hold.

However the rise of electric vehicles and household heat pumps threaten to reverse this trend, the report warned.

...

The report found that sustainable biomass generated more power than solar energy and provided a bigger reduction in wholesale power prices.

Over the last decade, biomass produced 88.1 TWh compared to 59.86 TWh from solar - despite the latter having a far greater installed capacity, the report found.

Meanwhile, wind energy delivered a quarter of the reduction in carbon emissions.

But as reliance on weather-dependent energy sources grew, the report warned that 'system operability' would become more difficult and called for more system support services and greater flexibility.

Well I think he already did, but it's actually a fair question in my opinion. If it's being felled and transported from North America, is it truly "zero emissions"? Or close enough to zero to squint and call it zero? I would like to see exactly how this is justified, because it sort of smells like a kind of accounting trick.

In truth, it does in fact emit CO2 in the burning of course, but we pretend that this CO2 doesn't count because it came from the atmosphere in the first place. Sure, OK, but instead of being bound up and trapped in the wood, we are putting it back into the atmosphere as CO2.

And of course, cutting down trees requires some kind of machinery that runs on fossil fuel. So does transporting the logs with trucks and probably the cutting into pellets too. Then it needs to be transported to a port and loaded into a ship that burns heavy fuel oil to be shipped across the ocean. And finally transporting from the port to the power generator. What does that all add up to?

Wind has surpassed hydro as most-used renewable electricity generation source in U.S.

In 2019, U.S. annual wind generation exceeded hydroelectric generation for the first time, according to the U.S. Energy Information Administration’s Electric Power Monthly. Wind is now the top renewable source of electricity generation in the country, a position previously held by hydroelectricity.

Annual wind generation totaled 300 million megawatthours (MWh) in 2019, exceeding hydroelectric generation by 26 million MWh. Wind generation has increased steadily during the past decade, in part, because the Production Tax Credit (PTC), which drove wind capacity additions, was extended. Annual hydroelectric generation has fluctuated between 250 million MWh and 320 million MWh in the past decade, reflecting a stable capacity base and variable annual precipitation.

Germany hits record 61 per cent renewables for month of February

[Including irrelevant but nicely ominous picture]

Renewable energy sources provided a record 61.2% of Germany’s net public electricity generation in February, according to figures provided by the Fraunhofer Institute for Solar Energy Systems (ISE), which also showed that wind energy provided nearly half of the country’s electricity during the month.

Fraunhofer ISE provides up to date tracking of Germany’s power sector through its Energy Charts website, and keen-eyed Twitter users highlighted record renewable figures with February now in the bag. Of the total 45.12TWh generated by Germany’s power sector, 27.63TWh, or 61.2%, was generated from renewable electricity sources.

According to at least one expert, this was a new monthly record for renewable electricity generation, smashing the previous record of 54% set in March of 2019. And while Germany has experienced higher shares of renewable electricity generation, these have been on a daily or weekly basis – such as in March of 2019 when the share of renewables in the country’s energy mix jumped to 72.4% – rather than this more impressive monthly record.

Throughout the month, Germany’s renewable energy sector regularly provided around 60% or above of the country’s electricity production – including over a dozen days around or above 70%.

Germany’s fleet of wind turbines generated a record 20.80TWh, or 45.8%, of the country’s electricity – similarly smashing the previous record of 34.7% set, again, in March of 2019. Unsurprisingly, then, wind electricity generation regularly provided around or above 60% of the country’s electricity generation.

Second in terms of contribution to Germany’s renewables power sector was biomass, which provided 3.74TWh, or 8.3% of total electricity generation, followed by solar with 1.86TWh, or 4.2%. Natural gas provided 10.2% of February’s total, while nuclear provided 11.5%. Coal provided only 17% of the country’s power in February.

Government set to reverse Cameron-era ban on onshore wind farm subsidies

Officials have told climate campaigners that onshore wind farms would soon be able to bid for subsidies from the Government.

The U-turn comes as ministers face increasing pressure to set out how the UK will hit its target of net-zero carbon emissions by 2050.

Land-based wind turbines have long been unpopular with grassroots Conservatives, leading the then-Prime Minister Mr Cameron to say he wanted to “rid” the countryside of the “unsightly” structures in 2015.

Onshore wind was officially blocked from bidding for financial support available to other forms of renewable energy in 2016, leading to a 94% decline in the number of new projects up to 2019.

Environmental groups have consistently protested against the ban, arguing that onshore wind is the cheapest new form of electric energy and has widespread public support.

US renewables groups hail landmark clean energy bill in Virginia

Legislation lays ground for 5.2GW offshore wind ambition and big deployments of solar and storage

Virginia's General Assembly passed landmark clean energy legislation that doubles its offshore wind goal to 5.2GW and clears the way for big deployments of solar and storage, in a move hailed by US renewable energy groups as transformational.

The legislation creates a mandate requiring that 30% or more of electricity comes from renewable sources by 2030 and sets a target of 100% zero-emissions by 2050.

The bill creates a pathway for Virginia to steadily reduce its dependence on fossil fuels, partly with incentives for 16.1GW of solar PV and 2.7GW of energy storage, as well as the offshore wind goal that's behind only New York and New Jersey among US states.

Tom Kiernan, CEO of the American Wind Energy Association (AWEA) called it “pro-business, forward thinking and comprehensive”, adding it will foster economic development across Virginia.

Wind provided record 40.2% of Oklahoma’s statewide electricity generation in 2019

Oklahoma’s use of wind energy to generate electricity continues to increase. A record 40.2% of all state’s generated energy in 2019 was powered by renewable technology, Oklahoma Power Alliance representatives announced Tuesday during a Clean Energy Day at the state Capitol.

In 2018, Oklahoma’s wind farms generated about 36% of the energy created inside the state, up from 33% the previous year.

“This data tells a strong story” about Oklahoma’s continued leadership in renewable energy deployment, Mark Yates, vice president of the Advanced Power Alliance and its policy director in Oklahoma, said Tuesday. He noted wind’s use to generate electricity in Oklahoma during the year only was surpassed by natural gas, which generated another 46.3%.

Alliance data showed Oklahoma ranked second among U.S. states for 2019 for the amount of energy its wind farms generated, and third for the amount of wind capacity installed. The alliance estimates more than $20 billion has been invested in renewable projects within the state. It also issued data showing the industry’s completed wind projects are ranked as a top-three taxpayer in 19 Oklahoma counties and 65 Oklahoma school districts. Projects’ owners made about$51 million in land lease payments to farmers and ranchers throughout 26 of Oklahoma’s counties in 2019. “These investments continue to transform Oklahoma’s rural economies by offering new career opportunities, circulating new income, creating sales tax revenue, and providing valuable ad valorem,” he said.

World's wind power capacity up by fifth after record year

Offshore windfarms and onshore projects in US and China fuel one of strongest years on record

The world’s wind power capacity grew by almost a fifth in 2019 after a year of record growth for offshore windfarms and a boom in onshore projects in the US and China.

The Global Wind Energy Council found that wind power capacity grew by 60.4 gigawatts, or 19%, compared with 2018, in one of the strongest years on record for the global wind power industry.

The growth was powered by a record year for offshore wind, which grew by 6.1GW to make up a tenth of new windfarm installations for the first time.

The council’s annual report found that the US and China remain the world’s largest markets for onshore wind power development. Together the two countries make up almost two-thirds of global growth in wind power.

Wind provided record 40.2% of Oklahoma’s statewide electricity generation in 2019

Oklahoma’s use of wind energy to generate electricity continues to increase. A record 40.2% of all state’s generated energy in 2019 was powered by renewable technology, Oklahoma Power Alliance representatives announced Tuesday during a Clean Energy Day at the state Capitol.

In 2018, Oklahoma’s wind farms generated about 36% of the energy created inside the state, up from 33% the previous year.

“This data tells a strong story” about Oklahoma’s continued leadership in renewable energy deployment, Mark Yates, vice president of the Advanced Power Alliance and its policy director in Oklahoma, said Tuesday. He noted wind’s use to generate electricity in Oklahoma during the year only was surpassed by natural gas, which generated another 46.3%.

Offshore wind 'could hit 200GW by 2030'

Energy Industries Council report raises concerns over supply chain's ability to keep pace with demand

Offshore wind capacity could grow to as much as 200GW of operational capacity by 2030, according to a new report by the Energy Industries Council (EIC).

EIC said in the 'Global Offshore Wind 2020' report that an increased awareness of the risks and effects of climate change is likely to lead to a greater focus on decarbonisation efforts in the supply chain and means of component production.

Forecasts on the operational capacity by 2030 range from 164GW to 200GW, it added.

Other drivers of growth could be cross-sector and sector coupling, particularly around decarbonisation of offshore oil and gas platforms and the production of ‘green’ hydrogen via electrolysis using offshore wind, the report said.

The report provides an overview of the latest trends, technologies and processes across the global offshore wind sector, in addition to an in-depth look at projects and developments.

It also warned that as more projects are added to the pipeline, concerns have been raised on the supply chain’s ability to meet global demand, particularly for vessels, skilled labour and fabrication shipyards.

Wind Power Continues Its March Into The Energy Mainstream

Wind energy is becoming an increasingly important part of the energy mix around the world, as costs continue to fall and technology improves

Global economic activity is on hold at the moment, but 2019 was a boom year for wind energy, with more than 60GW of capacity installed around the world.

New figures from the Global Wind Energy Council’s (GWEC) Global Wind Energy Report show that installations were 19% higher than the year before and the second-highest ever. Total capacity is now 651GW. However, the market needs to grow even more if we are to meet our climate targets, the organization says.

China and the US dominate the global market for onshore wind projects, accounting for 60% of sales between them, while the offshore market is now 10% of the overall market, with 6.1GW installed in 2019.

2020 was expected to be a record year for the industry, with 76GW of new capacity forecast to come on line, but that figure is unlikely to be reached as a result of the Covid-19 pandemic. GWEC says that it will revise its 2020-2024 forecast in the light of the potential impacts of COVID-19 on the global economy and energy markets, and will publish an updated market outlook in Q2 2020.

The key driver for the sector’s growth was the growth in the use of auctions to procure capacity, which has helped to drive down costs around the world. More than 40GW, or two thirds of new capacity, was procured through auctions, double the figure for 2018.

Most installations were in established markets, with just five countries (China, the US, the UK, India and Spain) accounting for 70% of new capacity.

Total Becomes Latest Oil Major to Enter Floating Wind Market

Building on its solar momentum, Total this week invested in a U.K. floating wind project and acquired a French wind developer.

France's Total announced two significant wind deals in recent days, becoming the latest oil company to push into floating offshore wind as it builds on its existing momentum in the solar market.

Total this week bought an 80 percent share of the 96-megawatt Erebus floating wind project in the Celtic Sea from developer Simply Blue Energy.

Then on Friday, the company confirmed its Total Quadran subsidiary had acquired developer Global Wind Power (GWP) France from its Danish parent, adding a 1-gigawatt portfolio of wind projects in France.

Fellow European oil majors Shell and BP have built-up gigawatt-scale renewables portfolios, but the pace of Total’s recent activity could see it outshine them both.

Total has 3 gigawatts of renewables within its 7-gigawatt portfolio of low-carbon projects. By 2040, the company aims to derive 15 to 20 percent of its revenue from its low-carbon business.

Earlier this year, Total bought a 50 percent share of Adani’s 2.1-gigawatt portfolio of operational solar assets in India for \$510 million. In February, it signed two solar deals in Spain, including an outright acquisition of developer Solarbay’s 1.2-gigawatt development pipeline. And Total was part of the winning partnership in Qatar’s most-recent solar tender for an 800-megawatt project.

Re: Wind Turbines

Oil Companies Are Collapsing, but Wind and Solar Energy Keep Growing

The renewable-energy business is expected to keep growing, though more slowly, in contrast to fossil fuel companies, which have been hammered by low oil and gas prices.

A few years ago, the kind of double-digit drop in oil and gas prices the world is experiencing now because of the coronavirus pandemic might have increased the use of fossil fuels and hurt renewable energy sources like wind and solar farms.

That is not happening.

In fact, renewable energy sources are set to account for nearly 21 percent of the electricity the United States uses for the first time this year, up from about 18 percent last year and 10 percent in 2010, according to one forecast published last week. And while work on some solar and wind projects has been delayed by the outbreak, industry executives and analysts expect the renewable business to continue growing in 2020 and next year even as oil, gas and coal companies struggle financially or seek bankruptcy protection.

In many parts of the world, including California and Texas, wind turbines and solar panels now produce electricity more cheaply than natural gas and coal. That has made them attractive to electric utilities and investors alike. It also helps that while oil prices have been more than halved since the pandemic forced most state governments to order people to stay home, natural gas and coal prices have not dropped nearly as much.

Even the decline in electricity use in recent weeks as businesses halted operations could help renewables, according to analysts at Raymond James & Associates. That’s because utilities, as revenue suffers, will try to get more electricity from wind and solar farms, which cost little to operate, and less from power plants fueled by fossil fuels.

The use of "petroleum" has no place in a thread about windmills. There are no petroleum power plants of note other than ones used for emergency. Refineries use it to refine, but that's because from that perspective, it's practically free.

How's that? I understand coal is PRIMARILY used for power generation.

Primarily, yes.

But it's also very important in steel production.
'Tis true. Roughly half a ton of coal per ton of steel. And more to the point, only the best coal at that.

bituminous coal + oven - oxygen = coke + iron = steel
