Då tar vi det igen då:The U.S. Hit a Wind and Solar Power Milestone in March
Trots Donald Trump, har andelen vind- och sol-el fördubblats på mindre än fem år i USA. I mars 2017 var andelen el som kom från vind och sol 10%.

Återstår att se hur mycket koleldningen ökar nu när Trump och Pruitt gör allt för att användning av ren energi ska minska till förmån för olja och kol.
Sjunkande elpriser
Samtidigt som andelen förnyelsebar energi ökar så har priserna en nedåtgående trend de senaste tre åren:

Om solel i USA för mindre än 3¢/kWh:

Om vindel i USA för mindre än 3,2¢/kWh:

Förnyelsebart, rent och billigt – Vad kan man mer begära?
Hur kan någon vara så tokig att dom vill satsa på att bränna kol och olja?

Wind turbines are neither clean nor green and they provide zero global energy
Citat:
The Global Wind Energy Council recently released its latest report, excitedly boasting that ‘the proliferation of wind energy into the global power market continues at a furious pace, after it was revealed that more than 54 gigawatts of clean renewable wind power was installed across the global market last year’.
You may have got the impression from announcements like that, and from the obligatory pictures of wind turbines in any BBC story or airport advert about energy, that wind power is making a big contribution to world energy today. You would be wrong. Its contribution is still, after decades — nay centuries — of development, trivial to the point of irrelevance.
Here’s a quiz; no conferring. To the nearest whole number, what percentage of the world’s energy consumption was supplied by wind power in 2014, the last year for which there are reliable figures? Was it 20 per cent, 10 per cent or 5 per cent? None of the above: it was 0 per cent. That is to say, to the nearest whole number, there is still no wind power on Earth.

Big Wind’s Dirty Little Secret: Toxic Lakes and Radioactive Waste
Citat:
To quantify this in terms of environmental damages, consider that mining one ton of rare earth minerals produces about one ton of radioactive waste, according to the Institute for the Analysis of Global Security. In 2012, the U.S. added a record 13,131 MW of wind generating capacity. That means that between 4.9 million pounds (using MIT’s estimate) and 6.1 million pounds (using the Bulletin of Atomic Science’s estimate) of rare earths were used in wind turbines installed in 2012. It also means that between 4.9 million and 6.1 million pounds of radioactive waste were created to make these wind turbines.
For perspective, America’s nuclear industry produces between 4.4 million and 5 million pounds of spent nuclear fuel each year. That means the U.S. wind industry may well have created more radioactive waste last year than our entire nuclear industry produced in spent fuel. In this sense, the nuclear industry seems to be doing more with less: nuclear energy comprised about one-fifth of America’s electrical generation in 2012, while wind accounted for just 3.5 percent of all electricity generated in the United States.

Vi struntar i att länka till apokalyptiska miljövideor från Kina. Det skulle vara sååååå deprimerande en solig dag som denna, eller hur?
