Due to the fact that solar installation involves working with panels and equipment that produce several hundred volts of electricity in the sunlight, there are some very serious safety issues that must be understood before you consider installing solar panels or PV system components onto your home. Often, the work involved in solar installation needs to be done by a professional, permits need to be applied for and specific electrical standards (which often differ from one area to the next) have to be met. It is for this reason that there is also often a lot of improvisation involved when installing a solar power system.

Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, and other crop residues, manure, sugarcane, and many other by-products from a variety of agricultural processes.
