THIS IS ONE OF THE LEAST EXPENSIVE WAYS TO REDUCE CO_2

摘要

The rapid increase in the use of ground-source energy for building heating and cooling systems in the UK is a relatively recent phenomenon. We are inclined to view it as a new idea — there are only about 3,000 installations in the UK, most of these domestic. However, there are more than 900,000 installations in the US and 500,000 on the continent. In Sweden, more than 30,000 vertical borehole and 10,000 GSHP systems are completed each year, so the industry is well established and extremely robust and reliable. By 2010 Sweden expects to provide 30 per cent of its heating and cooling energy from GSHP systems.
