The sun is a vital part of life on Earth. Plants need sunshine to survive and proceed with photosynthesis, the water cycle is powered by the heat the sun gives off, and walking outside on a sunny day can cause people to feel rejuvenated. In addition, the light that the sun gives off has the potential to become the predominant source of energy for society as it exists today. This is because solar power is a form of energy that can be harnessed in a variety of different ways, has the ability to provide for a diverse range of needs, is becoming more affordable at a rapid rate, and is completely renewable. The sun could play such a large role in the future of humanity that one of the engineering grand challenges is “ make solar energy more affordable.”
This goal brings to light that the most substantial issue with solar energy is that it can often seem to be too expensive for the general public. Scientists and the government are working diligently to produce more cost efficient and affordable forms of solar energy by changing the materials they use and the methods used to harness the power the sun can provide. In his 2012 article “More Affordable Solar Power,” Dan Chiras adamantly points out that the price for solar panels are falling “thanks to increased demand, mass production and intense competition among manufacturers.” In addition, he points out that solar panels can last over 30 years and that government incentives reduce the price of solar systems substantially causing solar panels that originally cost tens of thousands of dollars to plummet in price.
Massive amounts of energy are produced by the sun every year, nearly 85,000 terawatts according to the 2009 Popular Science article “Solar Energy.” This amount of energy is expo...

...ally pay for a diesel generator on monthly payments for solar panels. The initial investment was slightly more costly, but Mr. Ali, and a large number of other Bangladeshi people, show immense pride in their solar powered huts. Their solar panels allow them to have power businesses and hospitals as well as providing a safe form of power.
This type of advancement is all thanks to scientists who are constantly trying to improve upon the inventions of others. Solar energy might not be the cheapest and most affordable source of energy right now, but scientists are absolutely laboring to change that fact. Progress can clearly be noted in the story of Mr. Ali, and in the fact that the price on solar energy is constantly being reduced. The future of humanity is shining brighter everyday, and the grand challenge goal of making solar energy more affordable is getting closer.

Solar Power: The Future of Energy Essay

- I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today. What if I answer 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)....   [tags: energy, fossil fuels]

Solar Power : The Second Largest Energy Consumption Nation Essay examples

- Solar Power Overview Solar power is essentially the conversion of the energy from the sun to usable electricity. The most common source of solar power utilizes photovoltaic cells to convert sunlight into electricity. These photovoltaic cells utilize a semi-conductor to absorb the radiation from the sun and when the semi-conductor absorbs this radiation it emits electrons, which are harnessed as electricity. The picture on the right depicts a similar setup to the same way the home rooftop solarpanels work....   [tags: Photovoltaics, Solar cell, Solar power]

Wind Power And Solar Energy Essays

- Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity....   [tags: Renewable energy, Fossil fuel, Wind power]

Essay about Wind Power And Solar Energy

- Wind is a form of solar energy that can be used to do work. The wind turbine is the actual device that is used to make electricity. Wind turbine looks like a fan, but don’t be fooled because it doesn’t work like a fan. Wind turbine uses wind to make electricity while a fan has a cord that needs to be plugged into an outlet to create electricity, so don’t mistake them for the same thing. Turbines can be used to make the majority of our electricity. The wind turns the three blades, next spins the shaft that connects to a generator to create what we see as electricity that can be used immediately or store for later use....   [tags: Renewable energy, Wind power, Fossil fuel]

Essay on Solar Power: Energy’s Bright Future?

- ... The two materials are stacked on top of each other, and are immediately attracted to each other because they are oppositely charged. They create an electric field between themselves, called the P-N Junction (Gleue). Sunlight is transmitted to Earth in the form of photons that disrupt the crystal structure of the two layers and free an electron. The P-N Junction carries the electrons through a wire to power machines. Currently this process if only 18% efficient because only 2/3 of photons contain enough energy to free electrons in the solar cell....   [tags: Environment, Energy, Fossil Fuel]
