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 is a complete free and healthy power? It is evident that solar energy is a healthy source of energy, which will help stop global warming all together, but it is economically efficient to switch everything to solar energy. Solar energy is capable of becoming the world's future power supply because, it is renewable, eco-friendly, and extremely efficient when strategically placed.
Water energy is a product that’s uses the energy created by the moving water or tidal power to power mechanical devices or creates electricity. Burning "biomass," including crop waste from farms, crops grown and even animal and human waste, can also generate energy for every day uses. Solar power is one of the best renewable resources known to man today. The idea of trapping the suns rays to convert it into energy and produces electricity, heat, or cooling devices. Solar power has a variety of advantages it is so effective, abundant and infinitely renewable it makes it one of the leading renewable sources used today.
First generation cells aim to make as many cells as possible, second generation aim to make highly effective solar panels, and third generation cells try to create the most cost efficient solar panels.

Due to the predictions of the depletion of oil in the near future, many countries start to depend on renewable energy sources. Since solar power is one of the best choices, many massive solar energy projects have been established. Whiticar et al. state some examples of enormous solar power projects. Firstly, the largest project is SEGS, located in Modjave Desert in U.S., which uses solar thermal technology to produce enough electricity for half-million people.
It is also a type of energy that humans have a lot of, the amount is almost endless. People who live far and isolated from electricity power plants can just use the solar panels that are installed on their roof for energy. Changing to solar energy will also help life on Earth greatly in the long run and will help slow disasters such as global warming. Solar energy is more significant than anyone could have imagined.

According to Eco Info in 2009, at the rate we are using fossil fuels at; we have an estimate of 46 years of oil, 63 years of natural gas and 119 years of coal. However if every Canadian home and every home across the world had solar panels they wouldn’t need to use fossil fuels to power their homes. Everyday solar panel technology is becoming much more efficient. “Every minute the sun bathes the Earth in as much energy as the world consumes in an entire year.” — (US Department of Energy web site, 2010). Now by harnessing this amount of energy the worldwide energy crisis will be solved.
Renewable Resources The sun exists as one of the highest abundant sources of energy. Yet the world neglects to implement solar technology as a dependable resource. Daily, Americans make the switch to solar energy and cut dependency from local utilities. One of the greatest advantages of harvesting solar energy stands that the sun shines for long durations throughout the day and the sun rises every day; hence, reliability. Other natural renewable resources are available such as hydro, wind, geothermal, biomass and nuclear energy.
Solar power is one of the most renewable sources of electricity in the world. The sun shines almost every day, therefore providing photons to power the solar panels for as long as the sun still shines. It can lower your electric bills to a miniscule amount and it’s very friendly towards the environment. Did you know that scientists at the German Fraunhofer Institute broke the world record for the most efficient solar cell? Their design uses a new cell structure containing four solar sub cells to become 44.7% efficient.
In order to competently compare photosynthesis and semiconductor-based solar cell's production of electricity i.e. solar cell electricity, they both must be defined. Photosynthesis is defined as, (Biology Online, 2010) “The synthesis of complex organic material using carbon dioxide, water, inorganic salts, and light energy (from sunlight) captured by light-absorbing pigments, such as chlorophyll and other accessory pigments.” According to Thomas gale, ( Thomas gale, 2006), solar cells create electrical energy by converting sun light into electricity by using photovoltaic effect. These processes are similar because they both require sun light, transform that sun light and both processes are environmentally friendly. Photosynthesis and semiconductor –based solar cell production of electricity have many differences.
