We can’t all install a wind turbine at the bottom of the garden, yet simply changing when we use electricity can make our power consumption greener. Some years ago, making a science programme for RTE radio, I was let into the inner sanctum where skilled engineers control the Ireland’s electrcity supply to meet the constant [...]

Veteran environment journalist Fred Pearce has started a new Green Wash column at The Guardian. His opening salvo examines the question of green electricity supply, and green energy tariffs — the scheme that lets British energy customers pay a premium for green energy.

I hadn’t known that Einstein had invented a novel type of fridge in 1930, together with Hungarian physicist Leo Szilard. I was even more intrigued to read that engineers at Oxford are reviving their elegant design, because it has no moving parts and is ideal to run on solar power. The physics fridge uses ammonia, [...]

Misleading energy ratings

Buy A-rated electrical appliances, we are told, because they are more energy-efficient. Not so, says Brendan Boardman of the UK’s Environmental Change Institute, writing in the latest edition of Chemistry & Industry magazine. It seems that it is easier for larger devices to achieve an A-rating, even though they consume more electricity on average than [...]
Electricity use and prices soars

Bad news but also some good news in yesterday’s report from Sustainable Energy Ireland on our soaring electricity use, and the ESB’s application for a 30% increase in the price of electricity. First the bad news. There are nearly 1.5 million households in Ireland now (up 43% since 1990); our homes are larger on average [...]
