Compared to insulation and draughtproofing, solar power can be seen as a high-tech - if not necessarily 'deep' - solution. Behind the technology, it's actually a simple and commonsense idea - harnessing the natural power of the sun - which is looking more and more cost-effective as fossil fuel prices rise. A recent SolarUK blog posting has some more on this:

SolarUK is best known as the designer of the LaZer2 solar hot water system, but it's also an installer of photovoltaics, and this side of the business could get a boost from April 2010 when the Government's proposed Feed-in Tariffs come into operation, giving microgenerating homeowners a guaranteed price for selling their energy to the national grid.

Making sustainable choices is gradually becoming more affordable.
