– originally posted at Alternative Energy To many people, the differences between “alternative energy,” “renewable energy,” and “clean energy,” might not be obvious. But each term is unique and has its own individual definition. These three terms are not all exactly the same. Alternative Energy When we speak of alternative energy, we refer to sources of usable energy that can …

Basic facts about home solar power systems A home solar power system has several standard components they are as follows: * PV Modules or solar panels (to turn solar energy into electricity) * A charge controller (this is an electrical device that prevents batteries from overcharging and from power running from the batteries into the solar panels). * Batteries, to …

Sources of electricity are everywhere in the world. Worldwide, there is a range of energy resources available to generate electricity. These energy resources fall into two main categories, often called renewable and non-renewable energy resources. Each of these resources can be used as a source to generate electricity, which is a very useful way of transferring energy from one place …

Today’s most significant sources of power is the wind energy It is fueled by the wind, meaning it doesn’t pollute the air unlike power plants which depends on combustion of fossil fuels like natural gas and coal. Wind is formed by the heating of the atmosphere and the earth’s rotation, making it an inexhaustible and least expensive renewable energy source today.

This article will describe how solar energy is created and cover some of its basic principles. Solar energy consists of the light and heat emitted by the sun, in the form of electromagnetic radiation. With today’s technology, we are able to capture this radiation and turn it into usable forms of solar energy – such as heating or electricity. Although …

It has being observed that the consumption of non renewable sources has caused more environmental damage than any other human activity. Electricity generated from fossil fuels such as coal and crude oil has led to high concentrations of harmful gases in the atmosphere. This has in turn led to many problems being faced today such as ozone depletion and global …

Whenever the sun is out, your home’s roof is exposed to home solar power. Why not harness that energy, reduce your electric bill and limit the amount of carbon dioxide you add to the atmosphere each day? Depending on where you live, your roof’s orientation, and the load your roof can bear, mounting photovoltaic cells (PVs) on your roof could …

Photovoltaic cells—those black squares an array of which comprises a solar panel—are getting more efficient, and gradually less expensive, all the time, thanks to ever-better designs which all them to focus the gathered sunlight on a more and more concentrated point. The size of the cells is decreasing as their efficiency rises, meaning that each cell becomes cheaper to produce …
