Solar energy is argued to be the most sustainable type of energy there is‚ but some argue that it isn’t actually as sustainable as others would like to believe. The reason for this is‚ like with the wind energy‚ manufacturing the solar panels has some reports call ‘environmental downsides’. However‚ it is also considered to be one of the most sustainable energy types because it has two forms – light and heat‚ both of which are important to us and the wildlife surrounding us. Plants need the light

Solar Energy The use of solar energy is increasing throughout the world. Solar energy is used to make light‚ run computers and to conserve energy. Today we used fossil fuel to run factories and make electricity but little do the people know‚ one day we are going to run out of oil because it’s not a renewable source. Then what are we going to do ? We would have no other choice then to start using the sun for energy‚ so why not start now ? Solar energy is one of the world’s

Analysis of Data In the first part of the experiment‚ we use a fan cart and first thing we do it to get the force of the fan cart by tying a string in the fan cart and hang a mass until the system is not moving that means that it is in equilibrium state. The tension in the string is equal so that the hanging mass multiplied by the gravitational pull of the earth which is 9.8 ms2 is equal to the force exerted by the fan cart. Then we remove the string and turn on the fan cart and then let it move

receives extremely large amounts of energy coming from the sun. Solar energy has become a number one option for a future reliable‚ greener energy source. An article by the National Academy of Engineering‚ Make Solar Energy Economical‚ has proposed this issue as one of the many challenges engineers face this 21st century. The academy emphasizes‚ the sun’s “availability far exceeds any conceivable future energy demands. It is environmentally clean‚ and its energy is transmitted from the sun to the Earth

Why Do We Need Solar Energy? 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

Korleyfah Mouth Chem 331 Thursday 2:00pm Dr. Lijuan Li 20A Preparation of CuCl2~2DMSO 20B Preparation of RuCl2~4DMSO Abstract In order to synthesize our metal complexes‚ we were able to make both Copper and Ruthenium metals. From this‚ we combined each metal complex with DMSO by refluxing the compound. The metal complexes were analyzed through their melting point and IR spectroscopy to determine whether the metal bonded to a Sulfur atom or an Oxygen atom of the DMSO. After analyzing the IR spectrum
