In many countries today, a lot is being said about harnessing renewable energy technologies – particularly in light of the rising oil prices.

Renewable energy is power which has been generated from renewable resources – in other words, it does not “run out” or eventually become depleted. It can be continuously re-created.

It’s not just the prices of oil that has people searching for clean and renewable energy sources. Global warming concerns, and problems created by international pollution, have triggered this concern as well. Governments around the world have begun to support research on improving the renewable energy technologies.

Currently, the five common renewable energy sources are biomass, hydropower, geothermal heat, wind, and solar power.

Biomass

Biomass consists of organic material which has been produced by animals and plants. Biomass energy uses stored energy from the sun. This is a result of the natural process which any plant uses to survive – photosynthesis.

Because we can always grow new crops and trees, biomass is considered a form of renewable energy. Furthermore, organic waste can be used to create biomass as well.

Some examples of commonly used biomass fuels are crops, wood, garbage, and manure. When these materials are burned, they emit heat which produces steam, that can in turn be used to create electricity. Some biomasses are converted into other usable energy forms, such as methane gas or biodiesel.

Hydropower

Hydropower is one of the oldest forms of renewable energy. It was used in ancient times to grind grain. Coal was once the only source of power in the United States. But in 1880, the first Hydropower plant was built, and since then, more of these have been erected in order to provide the people with electricity.

Geothermal Energy

Geothermal Energy comes from within the Earth itself. The steam or heat which stems from the center of the earth can be used to regulate the temperatures of buildings, and can be used to generate electricity as well.
Because water can always be replenished by rain, and because the earth’s core maintains its temperature, this is considered one form of renewable energy.

Wind Power

Even the ever-present wind can provide a renewable energy source. Wind is created as a result of the uneven heating on the earth’s surface, which causes air to move. Thus, wind power is essentially a bi-product of solar power. Wind propellers are used to collect the wind’s kinetic energy, which turns turbines that are in turn used to create electricity.

Solar Power

This form of renewable energy will be available as long as the sun shines. Solar energy can either be used as thermal energy, or it can be converted into electricity.

As a thermal energy, it can be used to heat water or spaces. Through the use of solar cells or similar photovoltaic devices, it can be used to create electricity. The heat of the sun can also be used to create steam, which turns turbines and thus produces electricity.

With the desire that exists for a power source that isn’t as polluting and dangerous as fossil fuels, many people now want to use renewable energy in their homes too. This article considers some of the sources of renewable energy and how they can be used in the home.

Anyone who is a homeowner has a lot of options to use renewable energy. These homeowners may be using renewable energy without even being aware that they are using it.

Anyone who uses solar powered lights in order to brighten their walkway, or who uses a solar cover on their roof or hangs their clothes out to dry is already making use of the renewable energy of the sun. Different other renewable energy options exist which can be taken advantage of and by so doing the environment can be preserved.

One of the most practical renewable energy options for a home is the use of space heating as well as domestic hot water. This consists of more than 50% the energy usage of a persons’ household. By using renewable energy we also experience a lot of cost saving benefits.

One way of taking advantage of renewable home energy options is during the design of a new house. Having a southern wall that takes advantage of the windows can maximize the use of the low sun that prevails in winter. If you add a roof overhand over your windows it also allows the higher summer sun to be blocked. On a cool day you may also open your windows in order to let the breeze cool of the house so you can make use of wind energy. This can be easily achieved by adding heat whenever there is winter and coolness during the summer. By doing this you reduce you heating and cooling costs quite naturally. You can also use day lighting in order to take full advantage of the sunlight during the day and take advantage of your daytime lighting needs.

Wood stoves have their advantages and only if you’re using wood, diseased wood or small pellets made from wood chips, crop waste and other organic material for burning. It is a renewable heat source which can be sued through space heating. Modern wood burning stoves are also much more efficient which makes them a more practical option.

A homeowner can make use of active solar heating. Solar water heaters make use of renewable solar energy in order to heat the water supply of a house. This makes use of the solar collector panels that are placed on a roof. Solar water also runs through pipes placed under these panels and it is heated directly by the sun. Water can also travel to a water tank that is placed in your home for personal use. Electricity is also a factor that you have to consider and it can be produced for a home using photovoltaic technology. This technology also runs on the same idea that a solar calculator is powered by. Solar energy is perfect for rural homes where it would be difficult to run an electrical line to.

Geothermal heat pumps use the heat that comes from the Earth in order to move heat from one area to another. What this system requires is that you use a network of underground pies in order to move heat exchange fluid. The heat pump moves this fluid and transfers it to buildings for use. Installation costs are around the same as traditional heating systems but the operational costs are substantially lower.

If you reside in the part of the windy country and you have some land available you can use a wind turbine in order to power your home and provide electricity for yourself. The location that you live in must be ideal in order for you to trap wind and you must be able to trap a certain amount of wind in order for it to work.
