News about Solar, Wind and alternative green power technologies

It looks like the effort to decide upon the best alternate energy sources are being scrutinized by many nations and in America, many local regions.  Justification of this is the negotiated Kyoto treaty with a principal idea to collaborate on an agreement between countries to reduce carbon emissions and pollutants.

Thus far these alternative energy sources are showing they can assist in reducing the quantity of bad emissions which come as part of the production process and with energy consumption. These resources are also spared as natural resources for the populations. An example of this is when a solar power panel generates electricity due to the sun’s rays, that sun will still be shining for other to enjoy for their own reasons. The most prevalent and popular supplies of renewable energy are what follows below.

Solar Energy:  Capturing the omni-powerful energy of the sun is hardly novel. Using the suns brilliant light and heat has been exploited for thousands of years. Technologies hurried advances have enabled us to now capture the sun’s rays in solar cell units. Beginning in the early fifties solar cell usage has been evolving steadily and has made some admirable advances. It works by turning the sun’s heat into electricity.

Photovoltaic cells are installed on roofs and can be utilized to heat water with the sun’s energy. The water moves to a stowage tank and stored until it is ready to be used. However, science and technology is not needed to reap the benefits of solar power. Just simply open your curtains or blinds on a day when the sun is shining!
Up to this point the problem with solar power is it is inconsistent. It cannot be used in the evening hours or on days when the weather in inclement. To remedy this problem, commercial providers have begun to build solar power stations but these are quite costly to construct so their use has been limited up to now.

Wind Energy:  Yet another source of energy that has been around since ancient times. The wind has been used by sailors, farmers and architects for a lot of years and has been recorded being used as far back as five thousand years ago. The wind powers the blades of massive wind turbines and this produces electricity via an electrical generator. Years ago, windmills were designed to assist machinery in performing certain labor intensive functions. These included water being pumped, grain being processed, all essential to the farmers for their production.

Today we have huge wind farms which provide electrical capacity. The electricity created is then transferred to the nations power grids  and also smaller turbines owned by some people to distribute too out of the way regions and residences. The advantages of this kind of power are numerous. Starting with no byproducts left over from production that could damage the environment. There is no chance we could hit “peak wind” issues as we will encounter with oil sometime soon. A drawback of wind energy is that it too is inconsistent and directions vary so turbines must be engineered to rotate with the way the wind is blowing.

Geothermal: This form of energy is sourced out from the earth itself. Particular locations have holes drilled into them where magma and radioactive decomposition can be found that generates steam. The steam is then sanitized and is utilized to move turbines, the turbines are then what powers the generators for electricity.
The problem with geothermal energy is that is very expensive to manufacture. In order to make sure that proper precautions are in place for hazardous byproduct handling the facilities are required to be built to specific codes. It is considered a renewable energy source though since the crust of the earth continues to decay which restocks the heat.

Hydroelectricity:  The utilization of this form of power production also goes back to early times. Ancient Greece and China had used water wheels in their quick current rivers to revolve the stones in mills and other apparatuses. Hydroelectric facilities are still using the same theories these days as were used back in the day of Aristotle. The principals remain the same but some variations to the process are current. Today the force of the water is used to move the turbine which then powers a generator to create electricity.

The plan is we use the kinetic energy of the water and to ensure stable water supplies we build dams to retain and regulate water flow. When more power is required then the dam is opened and water is powered through.

There are of course issues with using hydroelectricity as well. Certain people say it creates risk for fish and water plants on each side of these dams since the flow of water is hampered it alters the balance and the silt and its nutrients could also be affected by the process.

Biofuels:  also qualifying as a source for green power. They have also been around for some time now but of late they are beginning to draw some attention. When plants grow they create biomass and this can be used to create biofuels or can be used themselves as a fuel. When produced through agricultural means biofuels like biodiesel  and ethanol can be burned in combustion motors and boilers. Biofuel releases a stored chemical energy within it. Motorized vehicles use liquid biofuel and it is both innate and renewable and as a domestic fuel source can also be used for diesel motors.

It is produced from vegetable oils such as soy for the most part and corn. Interestingly, diesel engines were engineered initially to run on vegetable oil. Biofuels do not contain any petroleum, they are non toxic and biodegradable. Biofuels do not create pollutants  in the air since they are not emitting anything toxic. The Environmental Protection Agency or [EPA] has only approved biofuels since they have passed all health and clean air testing and they meet the codes of the California Air Resources Board or [CARB]

It really is remarkable how nature provides for us when you understand how Renewable energy sources work and where they come from. It is also our responsibility to ensure that future generations can also enjoy these resources. Whatever fuels our belief systems, we are all aware of how damaging climate change is today. Currently in the United States only seven percent of green power sources are being used across the country. There is still time to make the necessary changes to modify the outcome of global warming provided we continue to push for further political interest and funding for these energy sources. Many of these power options are available for residential use so begin to do your own investigation into renewable energy sources today.
