And this on solar panels in the UK Daily Mail by Lauren Thompson:
"Solar panels that cost up to 16,000 pounds will knock just 70 pounds a year off household bills, which is almost half the original estimate, energy experts have admitted.
Environmental advisers the Energy Saving Trust (EST) has cut its estimate on how much households could save on their electricity bill using solar panels from the previous 120 pounds a year.
The EST had estimated that about 50% of the energy produced by solar panels is used in the home. It now says the figure is more like 25%. "
