Simon posted a topic in Renewable Energy's News and DiscussionsThe IEA keeps getting their solar energy predictions wrong in their yearly World Energy Outlook reports. Check out this graph by Auke Hoekstra, from the Eindhoven University of Technology, which shows how solar energy in reality is steeply increasing while the IEA keeps giving very conservative growth predictions, year after year. Why is it that the IEA keep getting their predictions wrong?
Renewable energy is crushing nuclear energy - and all other forms of power from dirty fossil fuels. There is only one new nuclear plant being built in the US, and all the existing nuclear plants are “bleeding cash” and struggling to stay competitive against renewables. In the draft report from the US Department of Energy that was leaked this past summer, even the Trump government admits that fossil fuels and nuclear are simply no longer economic compared to clean and modern renewable energy sources. And a recent study from the financial firm Lazard Ltd. shows that wind and solar energy are now cheaper than fossil fuels such as diesel, nuclear, coal, and in most cases natural gas. Clearly, governments and utilities around the world will from now on have a hard time justifying anything but renewable energy. So investing and building new renewables is now cheaper than just maintaining old nuclear and fossil fuel plants. This study was based on numbers from North America, a developed country where conventional energy sources such as nuclear and fossil fuels are less expensive to operate. In developing countries, conventional energy sources are much, much more expensive to build and operate. So the advantage renewable energy has in developed countries, such as the US, is even bigger in developing countries like China and India.
According to the Bloomberg New Energy Finance outlook, solar power is becoming increasingly affordable and in just a few years it could be cheaper than coal and even natural-gas plants, almost everywhere around the world. This means that solar power is going to kill fossil fuels much faster than we have previously thought. And it is not just solar power that is becoming an increasingly cheap energy source. Even in developing countries, like China and India, solar power is expected to start providing cheaper electricity as soon as the early 2020s. “These tipping points are all happening earlier and we just can’t deny that this technology is getting cheaper than we previously thought,” said Seb Henbest, a researcher at BNEF in London and lead author of the report. Even the cost of offshore wind farms are bound fall, the report concludes. There's no doubt about it: renewable energy is the future!
Let's kill this myth: renewable energy gets subsidies whereas fossil fuels and nuclear energy don't Short answer: Fossil fuels and nuclear energy have gotten subsidies for decades. Actually, fossil fuels have received government subsidies for 100 or so years. These days, fossil fuel subsidies reportedly total approximately $5 trillion globally each year. Despite tremendous health costs, climate costs, and countless premature deaths caused by pollution, these super rich and overly mature industries receive subsidies that serve no genuinely useful purpose for society. Renewable energy also receives subsidies, but not to the same degree.

Simon posted a topic in Renewable Energy's News and DiscussionsOn Wednesday this past week, wind produced 23% of Europe's electricity (and on a working day!). Germany 60%, Denmark 48%, Spain 37%, Austria 32%, and Netherlands 23%. Isn't that amazing? Don't let anyone tell you that renewable energy isn't a viable alternative to dirty fossil fuels. The source is here, if you want to check out how much electricity Europe generates from wind every day: https://windeurope.org/about-wind/daily-wind/
Here's an interesting article on how renewable energy can cause power prices to go negative: Power Prices Go Negative in Germany, a Positive for Energy Users. This story also reveals how our energy grids and battery technology is lagging behind the explosive growth of renewables in recent years. Thanks to low demand coupled with unseasonably warm weather and strong breezes over the weekend, wind power in Germany produced so much electricity that power prices dropped below zero "for much of Sunday and the early hours of Christmas Day". Ordinary consumers like you and me never experienced this price dip, but it's not the first example (and far from the last) of negative power prices in energy markets that have invested heavily in cleaner and renewable sources of electricity. These negative power prices show how our technology and our power grids have not yet been able to adapt to the increasing amounts of renewable energy being produced. Mainly it's our battery and distribution technologies that are lagging behind: But while we wait for further advancements in battery capacity and investments into smarter and better energy grids, we can still do a lot to mitigate these uneven effects: It's also worth pointing out, I think, that renewable energy is a decentralized energy source and doesn't work like older, larger and more centralized forms of energy. Renewable energy requires a different approach, where the consumers are also the producers of the power generated.
Simon posted a topic in Renewable Energy's News and DiscussionsThe world's biggest wind turbines have just come online at the Burbo Bank wind farm, off the northwest coast of England. And they are huge. Each wind turbine is fitted with three 80-meter-long blades. And a single revolution of one of these blades can power a single home for 29 hours. The Danish firm DONG Energy have installed 32 of these massive turbines, and together they will generate enough power for 4 million homes.
