Green energy also referred to as renewable or sustainable energy are energy provisions that have no long term impact on the environment and are replenished by nature. They meet the energy requirements of the present without compromising the ability of future generations to meet their needs. Unlike the use of fossil fuels which cannot be renewed and emit high levels of CO2 into the earth’s atmosphere, green energy generators such as hydroelectricity, solar energy in the form of PV and solar panels, tidal power, and biomass do not contribute to greenhouse gases and can therefore lower the carbon footprint.

Friday, January 13th, 2012What is Passive Solar Design (PSD)?
Tuesday, August 25th, 2009PSD basically optimises a building’s form, fabric, and orientation to maximise solar gain from autumn to spring, whilst minimising it during the warmer part of the summer. At the same time, daylighting is maximised at all times.
What is Solar energy?
Tuesday, August 25th, 2009Solar energy is the energy of sun light. The temperature of the Sun’s surface reaches to a value of approximately 5,762 K. The Earth’s perimeter of 40,000km results in an intersected sun power of 174,000 TW. Attenuation by the atmosphere results in a peak intensity at sea level of around 1 kW/m2, giving a 24 hour annual average of 0.2 kW/m2 and a 24 hour annual average power of 102,000 TW. This commands the environment and maintains the life support system of the Earth’s ecosystem and all forms of renewable energy with the exception of geothermal energy. The solar energy reaching the earth’s surface surpasses 10,000 times the current global energy demand.
