Essay on Why Do We Need Solar Energy - 1384 Words

Why Do We Need Solar Energy? nbsp;nbsp;nbsp;nbsp;nbsp;With the world’s natural resources depleting rapidly, humans must find a way to compensate. This society has milked oil, coal, gasoline, lead, uranium, and many other of these reservoirs in our Earth for hundreds of years and much has been done. Asphalt was used for our roads and highways, coal was originally used for heat before there was oil, and even water was used as a form of electricity on many rural farms. Luckily, more companies around the world are waking up to the fact that these resources will not be around forever, and that in the near future, other forms of energy will take heed. Solar energy, or energy powered by the sun, is one of the most promising. Since the†¦show more content†¦This was first discovered during the 18th century and the PV cells themsleves were developed at Bell Labs in 1950 primarily for space use. Today, the Hubbell telescope uses solar panels for its energy requirements. NASA continues to regularly use solar energy with much of their machinery, since electricity is dangerous in space. The cost for PV cells has dropped in the last few decades and now many rural health clinics can use it for refrigeration, water pumps, and for small scale power generation. Also, EXXON is the second largest producer of solar cells. It’s also very important to mention wind turbines, the modern equivalent to the windmill. These are mounted on a tower to capture the most energy. The â€Å"lift-and-drag† of the wind causes the rotor, which mounts the blades, to spin and the turning shaft spins a generator to make electricity. You may be asking â€Å"how does this relate to solar power?† Well, pressure variates between areas because of solar energy. This gives the power to these wind turbines. nbsp;nbsp;nbsp;nbsp;nbsp;Many other parts of the world have done their part in the conservation of non-renewable resources. Although, when poorer countries are more rural and tend to be lower income, not much thought is given to alternate forms of energy or conservation. These countries have to export more goods than other countries because theirShow MoreRelatedWhy Do We Need Solar Energy?1401 Words   |  6 PagesWhy Do We Need Solar Energy?

Without drastic change in the way the human race interacts with the world, this trend will continue. This is why we need to begin integrating environmentally friendly habits now, so we can begin to repair the damage. Of course, it should be said it’s not economically possible to completely change the way we behave overnight, but humanity needs to begin slowly moving towards a better way of life. One of the ways to do this would be integratingRead MoreWe All Rely On Some Sort Of Power Source For Our Household1748 Words   |  7 PagesWe all rely on some sort of power source for our household appliances, devices, lighting and entertainment needs. Sadly, the electricity used in the majority of our homes are powered by something dangerous, fossil fuels. Fossil fuels release carbon dioxide into the atmosphere and gradually disrupts nature and pollutes the air. Now imagine a reliable alternative source of energy that can fix this issue. Solar energy is the answer. We cannot rev erse the devastating damages caused by fossil fuelsRead MoreThe Importance Of Marketing In The Saudi Arabia Market1372 Words   |  6 Pages Today we are honored to have you all; members, employees, clients and companies, to launch our product and advertise for it in the Saudi Arabia market.

This kind of spending and reckless destruction of our environment will eventually have to stop. The question is, when it does what will we do? There are many other forms of alternative energy that are accessible to us right now. These energy sources will e ventually have to be used in the place of burning fossil fuels to power our world. PeopleRead MoreEssay about Solar Power: The Future of Energy1431 Words   |  6 Pagesanswer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there isRead MoreDevelopment of Solar Power Essay1245 Words   |  5 Pageslight) contains energy. Usually, when light hits an object the energy turns into heat, like the warmth you feel while sitting in the sun. But when light hits certain materials the energy turns into an electrical current instead, which we can then harness f or power† (Alivisatos). The method of transforming light into energy by human means is called PhotoVoltaics. Having this general knowledge, humankind created different devices made of a certain kind of material which could turn the solar power into energy;Read MoreImportance Of Solar Power1438 Words   |  6 PagesSolar Power This paper is going to be based on why should we use solar energy, how does it work, what are the advantages of solar power, and why should we apply solar power in the Dominican Republic. Did you know that the heat of the sun is about equivalent to burning a billion trillion tons of coal an hour? Even though only a small fraction of that heat ever reaches the earth is still more than enough to power up our whole planet. We are very certain that we have all heard about the terms fossilRead MoreEthanol Essay782 Words   |  4 Pagesdiversify our energy supply? In recent months, the new focus is the investment in research and development of alternative or renewable energy. Google has announced its plans to spend tens of millions of dollars in 2008 on the project known as Renewable Energy Cheaper than Coal (Reuters, 2007). The U.S. government also has put in place two programs called, Solar Energy Technologies Program and The Wind and Hydropower Technologies Program. These programs will research, develop and organize solar and windRead MoreThe United States Uses Fossil Fuels For 81 Percent Of Its998 Words   |  4 Pagesfuels for 81 percent of its the total energy. It is estimated that the world will use all of the fossil fuels sometime in the next 50-100 years. Either we need to find a way of slowing down the use of fossil fuels or we need to convert to a new source of energy. Renewable energy is the most viable option because we cannot run out of renewable energy. The convergence of Las Vegas and Google are examples of why, as a country , we need to use more renewable energy. The United States is the second biggest
