“Green energy is the way of the future” say environmental advocates. They argue that the transition away from fossil fuels is inevitable and inexorable, desirable. Some brazenly claim that the entire world could be powered by renewables as soon as 2030—assuming the governments’ subsidies don’t dry up. But is their exuberance justified? No.
Although renewable energy capacity has grown by leaps and bounds over the last three decades (wind power capacity grew on average 24.3 percent per year since 1990, and solar by 46.2 percent), renewable energy still generates an insignificant proportion of mankind’s power, and their rapid growth is not sustainable.
The truth is that after decades of beefy government subsidies wind power still meets just 0.46 percent of earth’s total energy demands, according to data from the International Energy Agency (IEA). The data includes not only electrical energy but also the energy consumed via liquid fuels for
