Letter: Brutal plans for energy conservation
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Sir: Marcus Rand's letter (15 May) made some very strong statements concerning the benefits of solar power. Statements which are dangerous to the credibility of the environmental lobby.
Your report (12 May), cited by Mr Rand, gave the cost of the new solar array as pounds 80,000. With a lifespan of 25 years, that is pounds 3,200 per annum. A large electricity bill indeed.
Irrespective of the economic issues, it is worth considering the environmental impact of mass-produced solar cells. Mass production means lower costs, lower lifespans to sustain a market, and hence a greater use of some fossil- derived chemical "nasties" Greenpeace has and does campaign against. What happens at the end of the cells' life ? Landfill? Recycling? Further, photo-voltaic arrays require batteries. Batteries are not exactly eco- friendly.
Our over-reliance on a small number of energy sources is much to blame for our current problems. Becoming reliant on photo-voltaic cells will not eradicate environmental problems. It will just create new ones.
They do have a role to play in new large-scale building projects or the renovation of older large buildings, where the cost can be justified, but not the replacement of our existing fossil power supplies. The many technologies which need to be considered include bio-gas, fuel cells, offshore wind turbines and the harnessing of novel energy sources such as landfill gas
