Solar Energy for the UK

Using solar energy reduces our consumption of, and dependence on, conventional fossil fuels and can help reduce emissions of harmful greenhouse gases, principally carbon dioxide CO2.
for example;
1 kWh of water heated by;
Mains Electricity - results in 0.43kg of CO2 being released (at a power station)
Natural gas - results in 0.19kg CO2
Diesel or heating oil (0.086 litres) - releases 0.35kg CO2 (in a typical domestic boiler)
Coal burning 50kg - releases around 121kg CO2

An average 3 bedroom semi is responsible for emitting around 4200 kg of CO2 per year.

Why should I consider solar heating?
With conventional energy prices rising, alternative ways of making power has to be renewable energies.

Hot water heating is the second highest energy cost in a typical household.

The average home currently uses about 3,300 kWh of electricity a year.
The average annual bill is calculated on the assumption that a household will use 3,946kWh of electricity and that generating costs will be 38% of an average bill. The remaining 62% consists of transmission costs, assorted levies, suppliers markup and huge profits for your current heating supplier.

In addition, home owners should consider the financial benefits.
Now is the time to consider one of the best investments you could make. The sooner you install solar panels, the sooner you will reach the point that these solar panels will have paid off the initial investment and provide truly free hot water.
