The past few weeks have seen extraordinarily high wholesale electricity prices in South Australia, averaging (as of 23 July) A$321 per megawatt hour, compared with A$80 per MWh for July 2015.
Low-carbon electricity from wind and solar farms will be cheaper than gas and effectively subsidy-free by 2020, says the Committee on Climate Change (CCC).
A new analysis from the government of Denmark found that wind power is by far the cheapest new form of electricity in the country.
Can ammonia become the world’s go-to liquid fuel and renewable energy storage medium? One entrepreneur thinks it can.
After years of delays and legal battles, several offshore wind projects seem poised to be launched off the U.S. East Coast.
Following on my recent post bidding Farewell to The Oil Drum, I’d like to have a look at what I view as our longer term future for energy production and consumption.
To what degree is it necessary, possible or desirable to rely on a massive, state, national or global-scale infrastructure build-out to save us from climate catastrophe and energy depletion?
Perhaps the biggest shortcoming of solar and wind power is their intermittency. In locations like Hawaii, where I live, wind and solar power are already competitive on price. My fossil-fuel supplied electricity typically costs above 40 cents a kilowatt-hour, and wind and solar power can compete with that. But since they can’t supply power that is available on demand (firm power) they must be backed up by power sources that can provide power when the sun isn’t shining and the wind isn’t blowing.
