Solar technologies are broadly characterized as either passive solar or active solar depending on the manner they capture, transform and distribute sunlight. Active solar approaches incorporate the use of photovoltaic panels, collectors, with electrical or mechanical equipment, to transform sunlight into helpful outputs. Passive solar approaches incorporate orienting a building structure to the Sun. Active solar technologies boost the supply of energy and are regarded as supply side technologies, while passive solar technologies reduce the need for alternate sources and are commonly considered demanad side technologies.
Hydroelectricity is electricity generated by hydropower which is the production of power through use of the gravitational pressure of falling or flowing water. It is the most extensively used type of renewable energy. once a hydroelectric complex is built, the undertaking produces no immediate waste, and has a significantly lower output level of the greenhouse gas carbon dioxide than fossil fuel powered energy plants.

many hydroelectric power can come from the prospective energy of dammed water driving a water turbine and generator. In this case the energy extracted from the water is dependent on the volume and on the variation in height amongst the supply and the water’s outflow.
In geology, geothermal refers to heat sources within the planet. The planet’s internal heat was initially generated throughout its accretion, thanks to gravitational binding energy, and since then additional heat has continued to be generated by the radioactive decay of elements such as uranium, thorium, and potassium.Follow the link power supplies
LEDs present quite a few positive aspects over conventional light sources such as lower energy consumption, longer lifetime, enhanced robustness, more compact size and swifter switching. Nevertheless, they are relatively expensive and call for more exact current and heat administration than conventional light sources.
A fuel cell is an electrochemical conversion system. It creates electricity from fuel and an oxidant which respond in the existence of an electrolyte. The reactants circulate into the cell, and the reaction products circulate out of it, while the electrolyte stays within it. Fuel cells can work essentially constantly as long as the necessary flows are taken care of.
Fuel cells are different from electrochemical cell batteries in that they consume reactant from an external supply, which must be replenished — a thermodynamically open system. By distinction batteries store electrical energy chemically and hence symbolize a thermodynamically closed system.

The performance of a fuel cell is dependent on the amount of power drawn from it. Drawing additional power implies drawing additional current which increases the deficits in the fuel cell. As a common rule, the more power (current) drawn, the lower the efficiency. Most losses manifest themselves as a voltage drop in the cell, so the performance of a cell is pretty much proportional to its voltage.
