The easy solution adopted by the Greens to the so-called environmental crisis involves abandoning fossil fuels and putting in place a capitalist economy based upon renewable energy. Actually, most Greens are radical Leftists, and when scratched, metaphorically, bleed red, red for communism. But, neither capitalism, or communism are sustainable on so-called renewable energy sources, which are anything but. Converting the vast majority of a nation over to electricity is not going to work, because the grid cannot cope with this massive expansion in demand, and this is true for all jurisdictions, including Australia and the US. The problem is that the main forms of renewable energy, wind and solar, are not fossil fuel-neutral, and will depend upon a massive use of fossil fuels to get to any where need the level required to make an attempt at replacing fossil fuels. But, the wind does not blow all the time, and the sun sets each day. Batteries can store electricity, but at a cost; they require extensive resources to produce, and massive numbers will be needed.
Meanwhile, while the environmentalist work to deindustrialise the West, the Green Left give their blessings to communist China to build coal-fired power stations, to rule the world. That is the real goal of Left and environmentalism is general: Chinese communist takeover.
