The Uses of Solar Energy

Posted by Larry Wood on April 30th, 2010 filed in Global Warming

The earth receives more energy from the sun in one hour than the power requirement of the world for the whole year. Solar energy is free, renewable, clean and sustainable. We know how to harness it and we know where to use it best. Below are the different uses of solar energy.

Grid-Tied Residential Homes

Solar energy can be used hand in hand with your current electricity provider. This is ideal to those who live in places where sunlight does not shine year round, to those who live in areas where electricity is cheap and to those who just want to use solar energy as a backup to their existing source of power. The idea is that if you have 2 sources of power, you can get uninterrupted power supply all the time.

One of the benefits of having a grid-tied solar energy system at home is that you can turn your electric meter backwards. This happens when you produce more energy than you use. The excess power that your system generates is sent out to the grid, which will be used by other households. As a result, your electric meter turns backwards and your electric provider will pay you for the amount of energy your system has produced.

Homeowners can use solar energy in producing electricity to power security lights around the house’s perimeter. Since these types of lights consume as much as 5 times more power than the household’s daily energy requirement, opting for solar energy system is very reasonable.

Solar power system may not be used to answer the entire power requirement of the household. Sometimes it is used to power particular equipment such as lighting, water pumping, cooking and water heating or other equipments that consume the most amount of energy.

Corporate Buildings

To save on electric bills, many companies and building owners install PV cells on their atria. On large industrial buildings, PV cells can be installed on rooftops. While the initial cash out is expensive, the amount of savings the system produces over the years will pay for itself.

Off-Grid Homes

If you have a cabin house or a farm house located far from the power grids, a solar power system can be your best source of electricity. Also, it is ideal if you need to power stand-alone sensing equipment and remote telemetry. Holiday homes that receive a substantial amount of sunlight can also benefit on this system.

Community halls, schools, clinics and other buildings that are not connected to any grid lines can use PV cells to generate power from the sun.

Signs and Street lights

Lights to brighten our street and street signs consume large amount of energy. This energy is drawn from electric providers that use conventional fossil fuels. To reduce the demand for this type of energy source, signs and street light can be installed with solar power systems that store power during the day and use it to light the streets at night. Many cities have solar panels attached to their street lights to save money and reduce fossil fuel burning.

Other Recreational Application

RVs and marine vehicles require small amount of power which are drawn from its engine. This consumes fuel and emits greenhouse gases. To reduce fuel consumption and greenhouse gases emission, owners prefer charging their batteries with solar panels.

Lastly, you got to check out the Energy Saving method that save the earth and my bill too. I didn’t know that I can make my own solar panel that only costs me less than one thousand dollar.

Dire Predictions: Understanding Global Warming - The Illustrated Guide to the Findings of the IPCCThe Intergovernmental Panel on Climate Change (IPCC) has been issuing the essential facts and figures on climate change for nearly two decades. But the hundreds of pages of scientific evidence quoted for accuracy by the media and scientists alike, remain inscrutable to the general public who may still question the validity of climate change.

Esteemed climate scientists Michael E. Mann and Lee R. Kump, have partnered with DK Publishing to present Dire Predictions-an important book in this time of global need. Dire Predictions presents the information documented by the IPCC in an illustrated, visually-stunning, and undeniably powerful way to the lay reader. The scientific findings that provide validity to the implications of climate change are presented in clear-cut graphic elements, striking images, and understandable analogies.

Unstoppable Global Warming: Every 1,500 Years, Updated and Expanded EditionSinger and Avery present—in popular language supported by in-depth scientific evidence—the compelling concept that global temperatures have been rising mostly or entirely because of a natural cycle. Using historic data from two millennia of recorded history combined with the natural physical records found in ice cores, seabed sediment, cave stalagmites, and tree rings, Unstoppable Global Warming argues that the 1,500 year solar-driven cycle that has always controlled the earth's climate remains the driving force in the current warming trend.

Trillions of dollars spent on reducing fossil fuel use would have no effect on today's rising temperatures. The public policy key, Singer and Avery propose, is adaptation, not fruitless attempts at prevention. Further, they offer convincing evidence that civilization's most successful eras have coincided with the cycle's warmest peaks. With the added benefit of modern technology, humanity can not only survive global climate change, but thrive.

Climate of Corruption: Politics and Power Behind The Global Warming HoaxNew revelations demonstrate how politics and powerful special-interest agendas have warped the most important scientific debate of the 21st century.

Melting glaciers, suffering polar bears, rising oceans—these are just a few of the climate change crisis myths debunked by noted aerospace expert Larry Bell in this explosive new book. With meticulous research, Bell deflates these and other climate misconceptions with perceptive analysis, humor, and the most recent scientific data.

Written for the laymen, yet in-depth enough for the specialist, this book digs deep into the natural and political aspects of the climate change debate, answering fundamental questions that reveal the all-too-human origins of “scientific” inquiry. Why and how are some of the world’s most prestigious scientific institutions cashing in on the debate? Who stand to benefit most by promoting public climate change alarmism? What true political and financial purposes are served by the vilification of carbon dioxide? How do climate deceptions promote grossly exaggerated claims for non-fossil alternative energy capacities and advance blatant global wealth redistribution goals?

With its devastating portrayal of scientific and government establishments run amok, this book is an invaluable addition to the tremendously popular literature attacking the scientific status quo. Climate of Corruption will bring welcome relief to all those who are fed up with climate crisis insanity.

Global Warming: The Signs and the ScienceMusic superstar Alanis Morissette hosts this engaging documentary focused on the challenges posed by climate change around the globe. Featuring in-depth interviews with everyday citizens from all walks of life living in the United States, Asia, and South America, the program also solicits the advice of scientific experts who opine on various strategies people can employ to cope with, or perhaps alter, their evolving world. 60 min.
