A lot has been said about the booming global capacities of solar and wind in the past few years. But wind works at a maximum 35% of the time for onshore and perhaps 45% for offshore wind. Solar PV is even lower, with 20 to 30% capacity factor. So, backup solutions are being sought. 2017… Continue reading How energy storage made headlines in 2017
Renewables currently generate very little of Puerto Rico’s electricity but hopefully this could change after Hurricane Maria.
That’s it ! Renewable energy sources and electric vehicles are progressing so fast around the world that according to a new study coal and oil use could peak worldwide in as little as three years.
With the current low prices of oil – they are now around $50 – one could think that solar, wind and the likes wouldn’t be this interesting as an alternative. Luckily, it isn’t the case at all. Let’s see why.
Now having to commute by car to get to my new job I can’t wait for having an electric car. But current prices are way to high for me to afford one. Luckily, this might change quite quickly. To AutoBlog Green : ” U.S. Energy Secretary Steven Chu estimates that plug-in vehicle battery costs will… Continue reading Electric cars batteries’ prices to drop by 2015
Remember my post on how a trillion had been invested in cleantech ? Well, the trend is accelerating as $260 billion (approx. 200 billion euros) were invested in 2011 alone as Bloomberg New Energy Finance reported. So, everything wasn’t so bad last year and especially not for the United States, which reclaimed their leadership from… Continue reading $260 billion were invested in Cleantech in 2011
” The South Korean government has announced that it intends to invest $35.4 billion in the renewable energy sector over the next five years as it aims at reducing its dependence on fossil fuels and build a green economy for the future.” “The South Korean government announced the ‘Green Korea’ plan in September 2008 which… Continue reading South Korea to invest $35 billions in energy
20 percent of America’s – and perhaps the world’s – electricity could soon come from wind and solar. Our societies thus need reliable, cheap and sustainable energy storage solutions. Concentrated solar could benefit from molten salts, yet wind energy doesn’t have yet its own solution. German and Swiss utilities are working on Compressed Air Energy Storage… Continue reading The critical issue of back up power
