There are various types of technology which can provide hot water for washing and bathing, heating and electricity. The costs of these vary significantly although there are grants available. It is best to get advice on what would be appropriate for your home as this will depend on many different things; from the age and size of your house and its location, to the type of existing heating and how many people live there. The Council can provide some information and there are numerous organisations that can give more technical advice.
Solar thermal hot water systems are one of the cheaper forms of renewable energy to install. These use the heat of the sun to provide hot water. It is a proven form of technology and can work alongside your conventional water heater. They can provide you with a third of your hot water needs. Carbon savings will depend on the fuel you use but can be around 325kg of carbon dioxide per annum.
There are grants available towards the cost of many types of renewable energy, such as Low Carbon Buildings Programme. The Council supports some local initiatives; for example, the Sussex Solar Scheme for installing solar heating panels.
Another way of reducing the carbon emissions from your energy use is to switch to a utility company that produces energy from renewable sources
