What’s wrong with renewable energy?

Ten things environmentalists need to know about renewable energy:

1.    Solar panels and wind turbines aren’t made out of nothing. They are made out of metals, plastics, chemicals. These products have been mined out of the ground, transported, processed, manufactured. Each stage leaves behind a trail of devastation: habitat destruction, water contamination, colonization, toxic waste, slave labour, greenhouse gas emissions, wars, and corporate profits. Renewables can never replace fossil fuel infrastructure, as they are entirely dependent on it for their existence.

2.    The majority of electricity that is generated by renewables is used in manufacturing, mining, and other industries that are destroying the planet. Even if the generation of electricity were harmless, the consumption certainly isn’t. Every electrical device, in the process of production, leaves behind the same trail of devastation. Living communities—forests, rivers, oceans—become dead commodities.

3.    The aim of converting from conventional power generation to renewables is to maintain the very system that is killing the living world, killing us all, at a rate of 200 species per day. Taking carbon emissions out of the equation doesn’t make it sustainable. This system needs to not be sustained, but stopped.

4.    Humans, and all living beings, get our energy from plants and animals. Only the industrial system needs electricity to survive, and food and habitat for everyone are being sacrificed to feed it. Farmland and forests are being taken over, not just by the infrastructure itself, but by the mines, processing and waste dumping that it entails. Ensuring energy security for industry requires undermining energy security for living beings (that’s us).

5.    Wind turbines and solar panels generate little, if any, net energy (energy returned on energy invested). The amount of energy used in the mining, manufacturing, research and development, transport, installation, maintenance and disposal of these technologies is almost as much—or in some cases more than—they ever produce. Renewables have been described as a laundering scheme: dirty energy goes in, clean energy comes out. (Although this is really beside the point, as no matter how much energy they generate, it doesn’t justify the destruction of the living world.)

6.    Renewable energy subsidies take taxpayer money and give it directly to corporations. Investing in renewables is highly profitable. General Electric, BP, Samsung, and Mitsubishi all profit from renewables, and invest these profits in their other business activities. When environmentalists accept the word of corporations on what is good for the environment, something has gone seriously wrong.

7.    More renewables doesn’t mean less conventional power, or less carbon emissions. It just means more power is being generated overall. Very few coal and gas plants have been taken off line as a result of renewables.

8.    Only 20% of energy used globally is in the form of electricity. The rest is oil and gas. Even if all the world’s electricity could be produced without carbon emissions (which it can’t), it would only reduce total emissions by 20%. And even that would have little impact, as the amount of energy being used globally is increasing exponentially.

9.    Solar panels and wind turbines last around 20-30 years, then need to be disposed of and replaced. The production process, of extracting, polluting, and exploiting, is not something that happens once, but is continuous and expanding.

10.    The emissions reductions that renewables intend to achieve could be easily accomplished by improving the efficiency of existing coal plants, at a much lower cost. This shows that the whole renewables industry is nothing but an exercise in profiteering with no benefits for anyone other than the investors.
