Solar Energy Advantages

Advantages Of Solar Power

People experience the power of solar energy everyday.  When you step outside and feel the heat from the sun you are experiencing the power of solar energy.  The sun releases energy 24 hours a day 7 days a week and every day you can benefit from converting that energy into usable energy for everyday life.

Solar Energy Is Sustainable

As long as the sun shines, getting energy from the sun is sustainable.  The common scientific knowledge on the sun reveals that the sun will continue to shine for billions of years.  So if sustainability is of interest to you, solar is a must to consider.

How To Harness Solar Energy

Solar energy can also be used to heat water with the help of solar water heaters and light the home with skylights.

Solar Panels Advantages

The movement to solar has taken off in recent years due to the fact the the federal government has introduced tax credits that make it very appealing to businesses and home owners to make the switch to  solar and other forms of green energy.

Solar Energy Advantages

Below is a list of some of the advantages of solar power

  1. Solar energy is free although there is a cost in the building of ‘collectors’ and other equipment required to convert solar energy into electricity or hot water.
  2. Solar energy does not cause pollution. However, solar collectors and other associated equipment / machines are manufactured in factories that in turn cause some pollution.
  3. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid.
  4. Many everyday items such as calculators and other low power consuming devices can be powered by solar energy effectively.
  5. It is estimated that the worlds oil reserves will last for 30 to 40 years. On the other hand, solar energy is infinite (forever).

More advantages of solar power includes:

  • Raw materials are renewable and unlimited. The amount of available solar energy is staggering — roughly 10,000 times that currently required by humans — and it’s constantly replaced. A mere 0.02% of incoming sunlight, if captured correctly, would be sufficient to replace every other fuel source currently used.

Granted, the Earth does need much of this solar energy to drive its weather, so let’s look only at the unused portion of sunlight that is reflected back into space, known as the albedo. Earth’s average albedo is around 30%, meaning that roughly 52 petawatts of energy is reflected by the Earth and lost into space every year. Compare this number with global energy-consumption statistics.  Annually, the energy lost to space is the combined equivalent of 400 hurricanes, 1 million Hoover Dams, Great Britain’s energy requirement for 250,000 years, worldwide oil, gas and coal production for 387 years, 75 million cars, and 50 million 747s running perpetually for one year (not to mention 1 million fictional DeLorean time machines!).

  • Solar power is low-emission. Solar panels produce no pollution, although they impose environmental costs through manufacture and construction. These environmental tolls are negligible,solar-panel however, when compared with the damage inflicted by conventional energy sources:  the burning of fossil fuels releases roughly 21.3 billion metric tons of carbon dioxide into the atmosphere annually.
  • Solar power is suitable for remote areas that are not connected to energy grids. It may come as a surprise to city-dwellers but, according to Home Power Magazine, as of 2006, 180,000 houses in the United States were off-grid, and that figure is likely considerably higher today. California, Colorado, Maine, Oregon, Vermont and Washington have long been refuges for such energy rebels, though people live off the grid in every state. While many of these people shun the grid on principle, owing to politics and environmental concerns, few of the world’s 1.8 billion off-the-gridders have any choice in the matter. Solar energy can drastically improve the quality of life for millions of people who live in the dark, especially in places such as Sub-Saharan Africa, where as many as 90% of the rural population lacks access to electricity. People in these areas must rely on fuel-based lighting, which inflicts significant social and environmental costs, from jeopardized health through contamination of indoor air, to limited overall productivity.
  • Solar power provides green jobs. Production of solar panels for domestic use is becoming a growing source of employment in research, manufacture, sales and installation.
  • Solar panels contain no moving parts and thus produce no noise. Wind turbines, by contrast, require noisy gearboxes and blades.
  • In the long run, solar power is economical. Solar panels and installation involve high initial expenses, but this cost is soon offset by savings on energy bills.  Eventually, they may solar panel poleeven produce a profit on their use.
  • Solar power takes advantage of net metering, which is the practice of crediting homeowners for electricity they produce and return to the power grid. As part of the Energy Policy Act of 2005, public electric utilities are required to make available, upon request, net metering to their customers. This practice offers an advantage for homeowners who use solar panels (or wind turbines or fuel cells) that may, at times, produce more energy than their homes require. If net metering is not an option, excess energy may be stored in batteries.
  • Solar power can mean government tax credits. U.S. federal subsidies credit up to 30% of system costs, and each state offers its own incentives. California, blessed with abundant sunshine and plagued by high electric rates and an over-taxed grid, was the first state to offer generous renewable-energy incentives for homes and businesses.
  • Solar power is reliable. Many homeowners favor solar energy because it is virtually immune to potential failings of utility companies, mainly in the form of political or economic turmoil, terrorism, natural disasters, or brownouts due to overuse. The Northeast Blackout of 2003 unplugged 55 million people across two countries, while rolling blackouts are a part of regular life in some South Asian countries, and occasionally in California and Texas.
  • Solar power conserves foreign energy expenditures. In many countries, a large percentage of earnings is used to pay for imported oil for power generation. The United States alone spends $13 million per hour on oil, much of which comes from Persian Gulf nations. As oil supplies dwindle and prices rise in this politically unstable region, these problems continue to catalyze the expansion of solar power and other alternative-energy systems.

If you have made it this far then you can no doubt see that solar power offers many advantages over traditional energy means.  Not only can solar energy save you money in the long run, it is also way better for the environment then fossil fuels and less dangerous then nuclear power.
