I would like to respond to a number of points raised in Rachael Richmond’s letter of 31 October.
It is undoubtably important that we find greener and better ways to produce electricity. We should, however, be extremely concerned if being self-sufficient in electricity is seen as more important than being self-sufficient in food.
It is hard to see how land that is currently graded as BMV (best and most versatile) could possibly be improved – certainly not by covering it in solar panels, seeding a monoculture of shade-tolerant meadow grass and then farming large numbers of sheep on it.
Large parts of the land would be in permanent shade and 40 years of rainwater run-off from the panels (with associated erosion and compaction) is unlikely to improve any soil.
Organic food production does not require “agricultural sprays”. What guarantees are there that herbicides will not be used in the control of saplings and weeds around the panels?
It would also be necessary to do a full comparison of the potential environmental impact of high-volume sheep farming (including faecal run-off to our rivers, greenhouse gas emissions and chemicals used in sheep-dips) versus using the land for other types of food production.
What would the effect be on birds and bats from covering large areas of countryside in panels, including the impact of tonal buzzing and humming? What effect also on the local climate of covering the land in this manner?
It should not be forgotten that the Pettywell proposal includes two acres to be covered by a battery-farm and associated concrete. The risk of fire and prolonged toxic output from these battery farms in such an event has meant that some countries have banned them.
Thousands of solar panels and the battery farm will need removing, transporting and recycling at the end of 40 years, not forgetting the fencing, CCTV masts, transformer blocks and associated concrete for these. Who will manage this and pick up the cost of this expensive process?
Global environmental issues should also be considered. There are increasing concerns from scientists and environmentalists about the impact of solar farms on the planet and the problems they are storing up:
-
By building solar farms on prime agricultural land some estimates suggest that “quadrillions” of calories have already been taken out of food supply – enough to feed millions of people.
-
The current (ageing) technology for solar panel manufacture uses raw materials that are causing illness and pollution during extraction, use toxic chemicals in production, produce toxic waste and use large amounts of water.
-
The transportation of the panels from China and across the UK will further increase the carbon footprint.
Huge swathes of Norfolk countryside are currently under threat from several bids for giant solar farms from organisations set to make massive profits from them.
It is important that “greenwash” marketing by these organisations does not go unchallenged.
Are we really doing future generations any favours by rolling out this ageing technology across our vital farmland and countryside or are we in fact creating even more problems for them?
