Landfill for solar it is after all. This is how you turn a problem into an opportunity. Derry, New Hampshire, has transformed an old landfill into a 2.25MW solar farm. Enough electricity to offset the consumption of around 500 homes. An estimated $4 MILLION in taxpayer savings over 25 years. Clean electricity generated on land that would otherwise have very limited use. No digging up farmland. No destroying forests. Just taking land once used for rubbish and turning it into something genuinely useful. From dumping waste to generating electricity. More of this, please.
