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.
If Jeremy Corbyn wins power in the next election he has promised to make the fight against climate change a top priority. Corbyn has argued that the only way to avert climate catastrophe is to fight the crisis with real and radical solutions. One of those solutions, Corbyn argues, is the full public ownership of Britain’s energy system. The Independent reports: Jeremy Corbyn vows to tackle ‘climate catastrophe’ by putting energy system in public hands Corbyn gives me so much hope! Finally, there is a leader that understands that the threat of climate change is real and that the only solutions are to radically transform our societies and economies.
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.
