Renewable Resources - Build Solar Panels for Power - Wind Energy Information - How to make energy efficient house and Save Cash!

Modern day energy conservation is imperative. The shortage of power, the rapid consumption of non-renewable energy, the ever-increasing demand for power supply, and the daily warnings about our environment are enough signs to tell us that it's time we do something.

So, what can we do? For starters, how about living off the grid? If I have startled you with that proposition, let me tell you that living off the grid not only helps the environment and helps save power; it also cuts down or eliminates your electricity bill. Now, those are tangible benefits that will make you feel good about your role on this earth as well as the savings to the family budget.

Home solar power systems are growing in recognition across the US and around the globe . The reason for this trend towards diy-how to make your own energy is easy to see, you stand to save a lot of money while saving the environment.

Another proactive step you can take today to make use of renewable energy is to begin your own wind powered energy project and build wind power turbines to produce electricity yourself.There are kits for building wind power turbines available, which can be costly, but with the right wind energy information it's possible to make your own wind powered electricity. Clearly how handy you are will be the deciding factor for buying vs. building but also keep in mind the cost. It is relatively easy and cheap to build wind power turbines in your own backyard.

When you take those factors into consideration why not take on a DIY wind and/or home solar power systems project for your household?

renewable energy resources are obtainable annually, unlike non-renewable energy resources which are ultimately exhausted. A clear-cut comparison is a coal mine and a forest. Although the forest could be exhausted, if it is managed appropriately it represents a uninterrupted supply of energy, vs the coal mine which after it has been exhausted is gone. The largest part of earth's accessible energy resources are renewable resources. Renewable resources total more than 93 percent of all U.S. energy reserves. Annual renewable resources were multiplied times thirty years for contrast with non-renewable resources. In other words, if all non-renewable resources were uniformly used up in 30 years, they would barely account for 7 percent of accessible resources every year, if all available renewable resources were developed.

In 2004, renewable energy provided roughly 7% of the world's power utilization. The renewables sector has been increasing extensively since the last years of the 20th century, and in 2005 the complete new investment was projected to have been 38 billion US dollars. Germany and China lead with investments of about 7 billion US dollars each, followed by the United States, Spain, Japan, and India. This resulted in an additional 35 GW (gigawatt is equal to one billion watts) of power during the year.

Solar power info:

Renewable energy sources are even larger than the conventional fossil fuels and in concept can with no trouble supply the world's energy needs. 89 PW (petawatt is equal to one quadrillion watts) of solar power falls on the planet's surface. Although it is not possible to capture all, or even the largest part, of this energy, using less than 0.02% would be sufficient to meet the existing energy needs. Barriers to further photovoltaic generation include the high price of manufacturing photovoltaic cells and dependence on weather patterns to make electricity. Also, solar energy does not supply electricity at night, which is a particular problem in high northern and southern latitude countries; energy requirement is highest in winter, while availability of solar energy is lowest. This could be overcome by buying energy from countries nearer to the equator throughout winter months. Globally, enrgy production is the fastest rising supply of energy, seeing an yearly average expansion of 35% over the past few years. Japan, Europe, China, U.S. and India are the major emergent investors in solar energy. Advances in know-how and economies of scale, together with demand for solutions to global warming, have led solar energy to become the most likely contender to take the place of nuclear and fossil fuels.

The accessible solar energy resources are 120,000 TW (terawatt is equal to one trillion watts). Less than 0.02% of these available resources are sufficient to totally supplant fossil fuels and nuclear power as our source of energy. Assuming that our rate of usage in 2005 remains stable, we will deplete conventional oil in 40 years, and coal in 154 yrs. In practice neither will in fact be depleted, as natural constraints will compel production to decline as the remaining reserves dwindle.

In 2007 grid-connected solar electricity was the fastest growing power source, with installations of all photovoltaics rising by 83% in 2009 to bring the total installed capability to 15 GW. Virtually half of the growth was in Germany, now the world's largest user of photovoltaic electricity (followed by Japan). Solar cell production increased by 50% in 2007, to 3,800 MW (megawatt is equal to one million watts), and has been doubling every two years.

The world's most powerful photovoltaic power plant is the 20 MW Beneixama photovoltaic power plant in Spain, although a 116 MW plant is under construction in southern Portugal, one of the sunniest places in Europe. The largest solar installation in North America is the 18 MW Nellis Solar Power Plant.

Wind energy information:

The accessible wind energy estimates range from 300 TW to 870 TW. Using the lower estimate, just 5% of the accessible wind power would supply the existing global power needs. The majority of this wind energy is available over the open ocean. The oceans cover 71% of the planet and wind tends to blow stronger across open water because there are fewer obstructions.

According to the Global Wind Energy Council, the installed capacity of wind power increased by 27% from the end of 2006 to the end of 2007 to total 94.1 GW, with over half the growth in the United States, Spain and China. Doubling of capability took about three years. The total installed capability is approximately three times that of the real average power produced as the estimated capacity stands for maximum output; actual capacity is generally from 25-40% of the estimated power.

Information for 100% off the grid power:

Photovoltaic energy is not accessible at during hours of darkness, making energy storage an significant concern in order to supply the constant availability of energy. Both wind energy and solar energy are irregular energy sources, meaning that all accessible output must be taken when it is available and either stored for when it is needed, or transported, over transmission lines, to where it can be used. Wind energy and solar energy can be paired, in locations that encounter greater wind in the winter and greater sun in the summer, but on days with no sun and no wind the difference needs to be made up in some manner.

Off-grid PV systems have traditionally utilized rechargeable batteries to store excess electricity. With systems that are still connected to the electrical grid, surplus electricity can be sent to the transmission grid. Grid monitoring programs give these systems a credit for the electricity they deliver to the grid. This credit offsets electricity supplied from the grid when the alternative energy system cannot meet demand, effectively using the grid as a storage mechanism. Credits are typically rolled over month to month and any remaining surplus is paid out yearly.

Eliminate your usage of non-renewable energy and help give the future generations a greener, healthier place.

It is not a pipe dream to achieve 100% off the grid power. There are high-quality DIY wind and home solar power systems guides to be had online that make the possibility of living off the grid not only feasible but cost-effective too.
