The New Zealand Greens happily retweeted that Costa Rica had not used a drop of fossil fuels for 75 days.
My first experiences with the environmental movement was through their opposition to the building of dams in south-west Tasmania. Maybe they have rehabilitated dams as a permissible energy source?

Solar and wind are a minuscule portion of world energy use.

Jacobson and Delucchi think we can replace all coal, oil, natural gas, and nuclear power by 2030 with wind, solar, and hydropower while fueling a fleet of electric cars.
How? By deploying 3.8 million 5-megawatt wind turbines, 5,350 100-megawatt geothermal plants, 500,000 1-megawatt tidal turbines, 720,000 0.75-megawatt wave power generators, 1.7 billion 3-kilowatt rooftop solar panels, 40,000 300-megawatt solar panel farms, and 49,000 300-megawatt concentrated solar power plants.
| Annual global investment target | Current global stock |
| 250,000 wind turbines | 225,000 wind turbines |
| 113 million rooftop solar panel systems | 11.3 million |
Delucchi and Jacobson estimate a price tag of about $100 trillion for their program.
That entails spending about $6.6 trillion per year from now until 2030, more than 11 percent of the entire world’s 2013 output of $75 trillion.
Naomi Klein cited Jacobson and Delucchi to support her proposition that 100% renewable energy systems is possible.
Utopia, you are standing in it!
