First a few facts!
Renewable energy is energy that is available from natural sources such as sunlight through solar panels, wind turbines, tidal, and geothermal heat which are naturally present in our environment. In 2008, about 19% of world energy consumption comes from renewable sources, with another 13% coming from traditional fossil fuels such as oil, coal, methane and natural gas, and peat moss, which is mainly used for heating, and 3, 2% from hydroelectricity.
new renewable energy sources that are small hydro, modern biomass, wind, solar, geothermal and bio-fuels were responsible for another 2.7%, growing at a rapid rate. The current share of renewables in electricity production is about 18%, with 15% of global electricity generation from hydro, and other 3% of the new alternative renewable or naturally occurring phenomenon. (reference source Wikipedia)
Wind energy
Wind energy is growing at a rate of 30% per annum, with a worldwide installed capacity of 158 giga watts (GW) in 2009, and is widely used in Europe, Asia and the United States. At the end of 2009, cumulative global solar installations exceeded 21 Giga Watts and Pico volts.
Solar power plants are a popular option for the production of energy in Germany and Spain
the adoption of wind energy is increasing.
naturally occurring winds and breezes can be used to run turbines. Modern wind turbines can produce from 600 kW to 5 MW of rated power, although turbines with rated output of 1.5 to 3 MW in general seems to be mostly for commercial use, the turbine power output is a function of wind speed to wind speed is then multiplied by the cube, so that the wind speed increases, power output increases dramatically. Areas where winds are stronger and more constant, such as the higher elevation sites, or offshore facility, are generally more preferred location for setting up wind farms.
Solar energy Solar energy is energy from the sun converts energy in the form of solar radiation. Solar power relies on photovoltaic and thermal solar motore.Djelomičan list of other applications including space heating and cooling through solar architecture, day lighting, solar water heating, solar cooking, a high temperature process heat for industrial purposes.
Solar technology is generally characterized into two categories, passive or active solar water or solar, depending on their unique features for recording, converting and distributing solar energy.
Active solar techniques include the use of photovoltaic panels and solar thermal collectors harness energy.That is then stored or converted uu usable source of energy or heat, light or electricity.
passive solar techniques include orienting the building to maximize use of the suns natural light and heat, and use of materials with low thermal mass or light dispersing properties, and designing floor plans architectually that naturally circulate air.
Economic Trends
all forms of energy are expensive, but as time progresses, renewable energy sources generally gets cheaper, while fossil fuels generally become more expensive.
fossil fuel situation is obviously just a matter of supply and demand, as supply goes down and demand is still growing. Demand and prices of fossil fuels continues to grow due to expansion and growth of new industrial based economies in China and India. That's why we never see our costs go down, until you take action.
I spoke of taking action through the use of a more responsible for their own consumption. And also through the exploration of alternative energy sources!
Questions about power consumption.
Q: How current is the American home use? 2008 average annual electricity consumption by U.S. residential utility customer was 11,040 kWh, an average of 920 kilowatt-hours (kWh) per month.
Q: How much total electricity used annually in the U.S. for cooling? According to estimates of the impact on the environment in 2008, plus about 500 billion kilowatt-hours (kWh) of electricity were used for cooling and ventilation. This includes commercial and residential end users.
residential sector used 227 billion kWh, which is an estimated 16% of total residential electricity consumption. About 22% is used by the commercial sector for cooling and ventilation, which is 291 billion kWh.U combined total was around 17.6% of the total electricity consumption in the United States in 2008.
Obviously, you already understand one of your biggest monthly expenses on your home energy consumption. Whether in the form of heating oil, propane, natural gas, electricity or.
So what can you do to save money?
The first and most obvious things are universal and easily trained. Change your habits! Make it a household project.
1 Turn off the lights in the room no one, or with
2 Keep the thermostat set at 68 degrees F during the winter months, and 80 degrees F during the summer months.
3 Use and buy energy efficient appliances, ie refrigerator, air conditioner, range, microwave, washer and dryer.
4 Turn your computer off when not in use.
5 Buy and use a new energy efficient light bulbs now available.
6 Install dimmer switches to the other lights so you can adjust the intensity .+
7 When buying a new TV to find one with the lowest energy consumption rating.
8 Use energy-efficient fans to circulate air between rooms in order to maximize heating and cooling effects.
9 Replace old windows and doors.
10 Check the proper amount of insulation of ceilings and walls.
11 If you can not afford to replace a door or window, you can be sure they are properly sealed with sealing tape and a new door or time. You can also seal the windows with clear plastic tape at the local hardware store.
explore alternative energy sources.
1 You can go solar, if you live in an area with lots of sunshine.
2 You can also look at wind, if you have enough wind to turn turbines.
3 Obviously you May not be able to go geothermal, or make your own hydro power sources, unless you have the right amount of land and these resources are readily available. However the cost of equipment can be prohibitive at best.
If you are able to generate enough power that you can go online, and maybe even sell some of their surplus Back to power companies. This sounds interesting does not it?
Making your own electricity.
A relatively new alternative to magnetic Generator. It does not get much press in the U.S., not sure why this is. But no, even though everyone is always talking about green energy or renewable energy sources as one of the most pressing issues facing our country and our economy.
Magnetic generators are green non-polluting electricity production machines. It does not produce substances such as exhaust fumes or toxins that pollute the air, water or land. They are truly the wonder of the environment due to these facts and so much more. Learn more about
