Energy Efficiency Energy efficiency, means using less energy to provide the same level of energy. It is therefore one method to reduce human greenhouse gas emissions. For example if a house is insulated, less energy is used in heating and cooling to achieve a satisfactory temperature. Another example is installing fluorescent lights or skylights, instead … Read more

Photovoltaic Electricity Photovoltaic (PV) electricity is a type of solar energy that converts sunlight into electricity using semiconductors. PV cells are made of materials that allow electricity to flow when light hits them. When sunlight hits a PV cell, it knocks electrons loose from their atoms. These free electrons flow through the cell, creating an … Read more
