CLEAN ENERGY

SOLAR PANELS
The sun radiates an immense amount of energy to the Earth. If it could all be tapped, the amount of solar radiation that reaches the globe every half hour would be enough to meet worldwide energy consumption requirements for an entire year.

There are two types of solar panel technology:
Photovoltaic panels: Save electric energy by converting the sunlight into electricity. By using photovoltaic panels with a battery, inverter and controller you can start using your own generated electricity for domestic units.
Thermal panels: Turn heat radiated by the sun into hot water. The liquid that circulates through these panels is heated by sunlight; this then passes through a coil in the water tank which in turn heats the water stored in the tank.

HEAT PUMPS
A heat pump takes the heat from water in pipes that are in contact with the ground, which can then be circulated through a heating system.

The average below ground temperature is between 8°C and 13°C.

Although this process cools the fluid, it can be re-circulated back through the ground where it will absorb more heat before being passed through the heat pump again.

Heat pumps do not generate electricity; they can however provide heating and can be operated in reverse to provide cooling. They do require electricity to operate, but ground source heat pumps are very energy efficient, producing up to five times the amount of heat energy for every unit of electrical energy needed to power it – this electricity can in turn be provided by renewable means.

WIND TURBINES
Wind represents a vast source of energy that has already been harnessed for hundreds of years - and wind power is currently one of the most developed and cost effective renewable energy technologies.

The modern wind turbine is quiet and is available in different sizes, depending on the required output. A small unit can attach directly to the roof and larger units will have their own support post.

The process by which energy is generated is fairly simple - when the wind blows the blades, the blades rotate a shaft. A generator converts the energy from the rotating shaft into electrical energy.
