Generating your own energy through renewable sources saves you money. You can also get paid for the energy you produce.
Once you have done as much as you can to make your home as energy efficient as possible, you might consider installing a system that uses a renewable source of fuel to generate energy. The system generates electricity or heat by using a renewable source of power such as the sun, wind or water.
The benefits of these systems are that they are free and do not produce any carbon emissions. Biomass is also deemed to be a renewable energy source as the wood or fuel crop is replaced by new planting and the new plants soak up the carbon emitted from burning the biomass.
