Solar water heaters generally employ a solar collector and a storage tank. The solar water heating collector is by far the most widespread solar energy conversion device and there are several millions in use around the world. There are many simple designs of collectors and water heating systems. Construction and manufacture is easily achievable in most developing countries.


A solar heating system for swimming pool is an economical alternative to expensive conventional heaters. Solar collectors capture free energy from the sun and use it to heat the swimming pool. The solar heating system extends the swimming season and reduce monthly fuel bills without depleting non-renewable fossil fuels.


Wind energy converts kinetic energy that is present in the wind into more useful forms of energy such as mechanical energy or electricity. Wind energy is a pollution-free, infinitely sustainable form of energy. It doesn't use fuel; it doesn't produce greenhouse gases, and it doesn't produce toxic or radioactive waste.


Solar PV (photovoltaic) uses energy from the sun to create electricity to run appliances and lighting. PV requires only daylight - not direct sunlight - to generate electricity. Photovoltaic systems use cells to convert solar radiation into electricity. The PV cell consists of one or two layers of a semi conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers, causing electricity to flow.
