Renewable Resources - Home Solar Power Systems - Wind Power Facts - How can you make a house energy

Modern day energy conservation is imperative. Everyday we read warnings in the news of our rapid consumption of non-renewable resources and the constantly increasing demand on our power supply.

So, what can we do? We can begin taking steps to getting 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. Trust me, you will feel good doing your part for our planet as well as for your family budget.

Home solar power systems are being talked about more and more 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.

Taking into account these advantages, it seems only reasonable that we would all undertake a DIY wind and/or home solar power systems project.

Renewable resources are available each year, unlike non-renewable energy resources which are in the long run depleted. A simple comparison is a coal mine and a forest. Despite the fact that the forest could be used up, if it is managed properly it represents a continuous source of energy, vs the coal mine which when it has been exhausted is gone. Most of earth's available energy resources are renewable energy resources. Renewable energy resources account for greater than 93 percent of all U.S. energy reserves. Yearly renewable energy resources were multiplied times thirty years for contrast with non-renewable energy resources. In other words, if all non-renewable resources were completely exhausted in 30 years, they would barely account for 7 percent of available resources every year, if all available renewable energy resources were developed.

In 2004, renewable energy supplied around 7% of the world's energy consumption. The renewables sector has been increasing significantly since the last years of the 20th century, and in 2005 the entire new investment was estimated to have been 38 billion US dollars. Germany and China show the way with investments of about 7 billion US dollars every, followed by the United States, Spain, Japan, and India. This resulted in an additional 35 GW (gigawatt is equal to one billion watts) of capacity during the year.

Solar power info:

Renewable energy sources are even larger than the conventional fossil fuels and in concept can without difficulty supply the world's energy requirements. 89 PW (petawatt is equal to one quadrillion watts) of photovoltaic power falls on the planet's surface. Despite the fact that it is not possible to capture all, or even most, of this energy, using less than 0.02% would be sufficient to meet the existing energy needs. Barriers to advance photovoltaic generation include the high price of building photovoltaic cells and reliance on weather conditions to generate electricity. Also, solar energy does not make electricity at night, which is a particular problem in high northern and southern latitude countries; energy requirement is greatest in winter, whereas availability of photovoltaic energy is lowest. This could be conquered by buying power from countries closer to the equator throughout winter months. Globally, solar generation is the fastest developing supply of energy, seeing an annual average increase of 35% over the preceding few years. Japan, Europe, China, U.S. and India are the foremost emergent investors in solar energy. Advances in technology and economies of scale, along 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 obtainable solar energy resources are 120,000 TW (terawatt is equal to one trillion watts). Less than 0.02% of these accessible resources are sufficient to completely take the place of fossil fuels and nuclear power as our source of energy. Assuming that our rate of usage in 2005 stays constant, we will deplete conventional oil in 40 years, and coal in 154 yrs. In practice neither will actually be depleted, as natural constraints will force production to fall off as the remaining reserves dwindle.

In 2007 grid-connected photovoltaic power was the fastest growing power source, with installations of all photovoltaics rising by 83% in 2009 to bring the total installed capacity to 15 GW. Nearly half of the growth was in Germany, now the world's largest user of solar 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 solar power plant in Spain, although a 116 MW plant is being built in southern Portugal, one of the sunniest places in Europe. The biggest photovoltaic installation in North America is the 18 MW Nellis Solar Power Plant.

Wind energy information:

The obtainable wind energy estimates range from 300 TW to 870 TW. Using the lower estimate, just 5% of the obtainable wind energy would supply the existing global energy needs. The largest part of this wind energy is obtainable 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 capability of wind power improved by 27% from the end of 2006 to the end of 2007 to total 94.1 GW, with over half the increase in the United States, Spain and China. Doubling of capability took about three years. The total installed capacity is approximately three times that of the actual average power produced as the estimated power stands for maximum output; actual capacity is generally from 25-40% of the estimated capability.

Information for taking steps to go off the grid:

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

Off-grid PV systems have traditionally utilized rechargeable batteries to store excess electricity. With grid-tied systems, extra electricity can be sent to the transmission grid. Net metering programs give these grid-tied systems a credit for the electricity they deliver to the grid. This credit helps pay for electricity provided from the grid when the alternative energy system doesn't meet demand, for practical purposes using the grid as a storage mechanism. Credits are normally rolled over month to month and any remaining surplus is refunded annually.

Make the future of your future generations secure by helping to give them a greener, healthier world. Cut down on the usage of non-renewable sources of energy.
