The power of the sun. Free energy.

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

To us at GreenDustries it seems such a waste that something as valuable and as powerful as the sun should be admired for the growth of plants and even the growth of humans but should be neglected for its ultimate ability to provide the one thing we so sorely need: natural energy.
According to the website, www. energyquest.ca.gov , “Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy’s uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes. To harvest the solar energy, the most common way is to use solar panels.”

We have always used the energy of the sun as far back as humans have existed on this planet. “We use the sun’s energy every day in many different ways. “When we hang laundry outside to dry in the sun, we are using the sun’s heat to do work – drying our clothes. Plants use the sun’s light to make food. Animals eat plants for food. Decaying plants hundreds of millions of years ago produced the coal, oil and natural gas that we use today. So, fossil fuels is actually sunlight stored millions and millions of years ago.” Indirectly, the sun or other stars are responsible for all our energy. Even nuclear energy comes from a star because the uranium atoms used in nuclear energy were created in the fury of a nova – a star exploding. The ways at which we can use the sun’s energy are numerous. By 1920, ten of thousands of solar water heaters had been sold, following the discovery of large deposits of oil and natural gas in the western United States,” according to Energy Quest. “As these low cost fuels became available, solar water systems began to be replaced with heaters burning fossil fuels.”

Today, solar water heaters are making a comeback. There are more than half a million of them in California alone. They heat water for use inside homes and businesses. They also heat swimming pools.
Solar energy can also be used to make electricity. To illustrate: Some solar power plants, like one in California’s Mojave Desert, use a highly curved mirror called a parabolic trough to focus the sunlight on a pipe running down a central point above the curve of the mirror, according to the site. The mirror focuses the sunlight to strike the pipe, and it gets so hot that it can boil water into steam. That steam can then be used to turn a turbine to make electricity. We can also change the sunlight directly to electricity using solar, or photovoltaic cells. These can be found on many small appliances, like calculators, and even on spacecraft.

So uses of the sun’s power come in all forms, shapes and sizes. All we need do is expand our thinking and invest in sustainable energy uses that make sense … and also make cents. We at GreenDustries believe that one day not too far away,those new clean and free energies will be harvested and part of our every day life, for a better and safer world.
This is our goal, while talking about it throughout our Social Marketing, we are doing our part to change to a less polluted planet when we introduced to you our PleatPak and Magic Bag, the only 100%Green Packaging for the “food industry on the go”….
