Renewable energy can't do job 20 Dec, 2015 | Modified 22 Dec, 2015 | Views 705
Today's renewable-energy technologies aren't a viable solution for reducing CO2 levels. The cost of using current renewables such as solar panels and windfarms to produce all or most power would be "beyond astronomical".
Gates: Renewable energy can't do the job. Gov should switch green subsidies into R&D
Retired software kingpin Bill Gates has given his opinion that today's renewable-energy technologies aren't a viable solution for reducing CO2 levels, and governments should divert their green subsidies into R&D aimed at better answers.
Gates expressed his views in an interview given to the Financial Times yesterday, saying that the cost of using current renewables such as solar panels and windfarms to produce all or most power would be "beyond astronomical". At present very little power comes from renewables: in the UK just 5.2 per cent, the majority of which is dubiously-green biofuel burning rather than renewable 'leccy - and even so, energy bills have surged and will surge further as a result.
In Bill Gates' view, the answer is for governments to divert the massive sums of money which are currently funnelled to renewables owners to R&D instead. This would offer a chance of developing low-carbon technologies which actually can keep the lights on in the real world.
Gates says he'll personally put his money where his mouth is. He's apparently invested $1bn of his own cash in low-carbon energy R&D already, and “over the next five years, there’s a good chance that will double,” he said.
“There’s no battery technology that’s even close to allowing us to take all of our energy from renewables," he said, pointing out - that it's necessary "to deal not only with the 24-hour cycle but also with long periods of time where it’s cloudy and you don’t have sun or you don’t have wind."
Gates is already well known as a proponent of improved nuclear power tech, and it seems he still is.
Renewable energy technology as it now is has no chance of powering a reasonably numerous and well-off human race. This is actually a very simple thing to work out, and just about anybody numerate who thinks about the subject honestly comes to the same conclusion - examples include Google renewables experts, global-warming daddy James Hansen, even your more honest hardline greens (they typically think that the answer is for the human race to become a lot less numerous and well-off).
