New offshore windfarms push UK renewables to record

Green energy provided almost a third of electricity between July and September

Major new offshore windfarms connecting to the grid pushed renewables to 33.1% of electricity generation across the quarter, up from 30% the year before.
Real progress! :WooHoo:

Or is it really?

Did the increase in energy production by renewables translate into an equivalent reduction in the burning of fossil fuels?
Global carbon emissions reached an all-time high in 2018, an extraordinary watermark in Earth’s history that underscores the need for faster and stronger action to address accelerating climate change, according to dozens of scientists.
No doubt all Trump's fault for pulling the US out of the Paris climate agreement.
A report released yesterday by a consortium of researchers known as the Global Carbon Project finds that global carbon dioxide emissions from burning fossil fuels are likely to have increased by about 2.7 percent in 2018, after a 1.6 percent increase in 2017.

The rise comes after a three-year period in which emissions remained mostly flat—providing hope to some climate activists that global carbon emissions had reached their peak. The increases in 2017 and 2018 seem to suggest otherwise.
So I am now just starting to get a little bit skeptical of stories like this.

Yes, it may be true that the wind farms are producing more electricity than last year, but is all of the electricity being produced displacing the burning of fossil fuels that would otherwise produce the same electricity? :notsure:

Record amount of new wind capacity financed in Europe last year - industry

LONDON (Reuters) - The amount of future new wind capacity in Europe financed last year rose to a record high, industry group WindEurope said on Thursday, as falling costs and increased competition made it possible for investors to fund more for less cash.

In total, 16.7 gigawatts (GW) of projects reached a final investment decision - 12.5 GW onshore and 4.2 GW offshore - 45 percent more than in 2017, WindEurope said in its annual report.

Funding for the new investments rose to 26.7 billion euros (23.2 billion pounds). Even though 45 percent more future capacity was invested in, the amount spent on the investments was 20 percent more than a year earlier, a sign that costs continue to fall.

“Cost reductions across the industry’s value chain and increased industry competition have made it possible for investors to finance more capacity for less cash,” it said.

The cost of generating electricity from wind power fell to 1.59 million euros per megawatt (MW) in 2018 from 1.93 million euros/MW in 2017, WindEurope said.

However, the report distinguishes between finance for future projects over the next few years and farms actually installed, saying the amount of capacity newly installed last year fell.

“Last year was the worst year for new wind energy installations since 2011 ... 12 EU countries didn’t install a single wind turbine last year,” said WindEurope’s chief executive Giles Dickson.

In the 28 European Union member nations plus Switzerland, Norway and Turkey, the amount of capacity added last year was 11.7 gigawatts (GW), 32 percent less than in 2017, due to poorly designed auctions and issues with permits, the report said. ... newsletter
