Solar Energy Essay Example for Free

Solar Energy Essay Solar Energy is one of the many renewable sources that is produced by the sun in the form of light and heat. It is one of the most important non-conventional sources of energy due to the fact that its free and we have plenty of it. Humans have been using it since ancient times. Solar energy can be use two ways, we can convert it into heat energy or it can converted into electricity. It has had a rapid growth in recent years, accounting for less than one percent of electricity used in the United States today. The market exceeds sales of 29 billion dollars and 1. billion of that money goes to the United States alone with California leading the way. Solar panels give off no pollution, the only pollution produced as a result is the goods and devices needed to make the panels. Some renewable fuels can be noisy like wind turbines, solar energy makes electricity quietly. Installing solar panels in remote locations is usually more cost effective than laying high voltage wires. It can be very efficient in large areas, and with technologies improving everyday, it allows for more efficient energy production on overcast and dull days. Another great example is that panels can be installed on top of rooftops which allows for more space. The use of solar energy to make electricity allows the user to become less dependent on the worlds fossil fuel supplies. This is very good for the environment. Just like everything good, solar energy has its cons. The cost it takes to make the cells for the solar panels can be very expensive and some houses may need more than one. Another example is that some panels required the sun all day, so that means that in the nighttime, the panels are not producing energy. Also weather can affect the efficiency of solar cells. Even with all the cons, the pros still outweigh the cons when it comes to solar energy. Take china for example, it has become the top country in green energy especially in solar power. It accounted for half the world’s production last year and the top three companies in China all said that the numbers are rising. Since they have become successful, more countries are looking towards solar energy. Shell has predicted that by 2040 more than 50 percent of the world’s energy will come from renewable sources. In the end, the future of solar energy promises to play a larger role thanks to the developments that could result in lower cost. As a matter of fact, the solar PV industry plans to provide half of all the United States electricity generation by the year 2025. That means that in the next few years it is expected that millions of households in the world will be using solar energy. More and more people especially architects are becoming aware and are recognizing the value of solar panels and learning how to incorporated into the building designs. This will be better for the environment and overall for the people. Who wouldn’t want lower electricity bills and greener world.
