At the very least, we should learn from Germany's costly mistakes. Germany's goal was to cut greenhouse emissions 90 percent by 2050 from 2005 levels. But instead of reducing its reliance on coal and natural gas for electricity production, just the opposite has happened. Following the accident at the Fukushima nuclear plant in Japan, Germany decided to close its nuclear plants. But despite huge subsidies, solar and wind power couldn't replace the lost nuclear power.
The Arkansas Public Service Commission says that is almost double the previous year and more than 40 times the number in 2007. The commission's data shows net metering in the state at the end of last year could churn out enough power, about 9 megawatts, for 1,000 typical homes based on industry estimates.
You report (4 July) that the cost of Hinkley C power station has just bumped up £1.5bn, and its completion date slipped 15 months. Notwithstanding, pro-nuclear politicians will assure us that it still represents good value for the consumer, despite the National Audit Office judging it "risky and expensive" (Report, 23 June). Had we invested that £1.5bn in green generation, what might it have bought? At current median project prices of £1.3m per megawatt (MW), we could have had 1,150MW of extra onshore wind turbine capacity. The Digest of UK Energy Statistics onshore wind load factor is 27.3%, therefore that extra hardware would on average generate 314MW of clean electricity, with no risk of reactor meltdowns, and without producing bomb material or the wherewithal for nuclear terrorism.
Germany hit a new milestone in renewable energy on Sunday, generating so much power at one point that customers were essentially being paid to turn on their lights or charge their phones. Quartz reports that around 1pm Sunday, about 87 percent of the power being used in Germany was coming from wind, solar, hydro, and biomass power plants. In 2015, the average was 33 percent. There was so much power being produced that the cost of electricity briefly dropped to - 149 per megawatt-hour, according to the Independent. The high mark in renewable power was credited to a particularly sunny and windy day and the relatively low energy use of a Sunday morning.
