Energy Sources Of Solar Energy

     In 1954 Bell Laboratories invented the first photovoltaic (or solar) cell, made from the semi-conductor silicon, and other elements. It was the first way to convert sunlight directly into electricity. When the space program was launched in the 60's, it

Solar energy is the conversion of power from the sun to usable electricity (Alternative Energy, 2014). The most common source of solar energy utilizes photovoltaic cells to convert sunlight into electricity (Alternative Energy, 2014). Photovoltaics use a semi-conductor to absorb the radiation from the sun, creating and emitting electrons, which are then harnessed and used as electricity (Alternative Energy, 2014).

the sun is a great and appendant source of energy, it's called solar energy. Solar panels were

The greatest energy that can be produced by the sun is electricity. Photovoltaics, or solar cells, capture the sun and convert it into electricity. Solar cells were discovered by the Europeans back in the 1870’s when they used selenium to develop the telegraph. They found that when light hits selenium it would produce and electrical current. Soon enough there were many scientists and engineers working on photovoltaic systems. Silicon and Selenium proved to be the two best elements to conduct electricity when light hits them. Photovoltaic systems (PV cell) work by converting the suns light into electricity. A semi conducting material absorbs the sunlight, that energy knocks electrons loose from their atoms, this allows the electrons to flow through the material to produce electricity. The further development of solar cells can be attributed to the satellite industry. Solar cells were expensive and there was no use for them until satellites came. Because it is impractical to tether satellites it became important to develop solar energy at any cost that would power these satellites. This created a sustainable market for solar power, the first of its kind.

Most of the processes that are critical for our day-to-day lives are driven by energy provided by the Sun. Energy from the Sun warms the planet and keeps the global temperature within a range that allows life to flourish. The energy stored in the food you eat can be traced back to the Sun, through the conversion of solar energy to chemical energy in the process of photosynthesis. You might think that the gasoline that makes your car run or the oil that

Solar energy is capable of providing a cleaner energy than most forms of energy generation, and solar energy is able to be generated economically. Solar energy reduces the amount of harm to the environment from energy generation, by providing a cleaner alternative. Solar energy also provides jobs for construction and installation of solar powered technologies.

Solar energy is rising throughout the United States. This source is mainly used in remote locations, but is becoming popular in urban areas. In 18 days of sunlight the earth receives an equal amount of energy stored in all of the earths reserves of oil, coal, and natural gas. Solar energy is produced by collecting sunlight with large, flat panels, made up of individual solar cells, and converting the sunlight into electricity. Solar energy is an alternative to fossil fuel and it is important to know the advantages, disadvantages, and the overall price.

Solar energy is energy that is collected from the sun that is then turned into electricity. The most common medium for using solar power is the use of solar panels. Through the use of solar panels people can use that harnessed electricity to power their houses, household appliances, their cars, even their towns and cities.

Solar energy has been used for a very long time. The first account of the use of solar energy was from the Greeks. They built their homes in a way that the sun would heat up their houses, even during the cold winters. Ancient Indians also used this method. Let's skip to 1839. In 1839, Edmond Becquerel observed that when certain material was exposed to light, it would create a small amount of electric current. This is the photovoltaic effect(A Brief). This led to John Ericsson developing what he said to be a solar powered steam engine in 1870. Now let’s jump to the late 1950s when a one-watt solar cell costed $300 and a commercial power plant watt cost $0.50 per watt. A scientist was able to demonstrate how a car can

There are two main forms of solar power: The use of photovoltaic, or PV, cells, and the use of thermal energy from the sun. Photovoltaic cells exploit the photoelectric effect, which converts the protons from the light of the sun into electrons, which can be converted into energy. Photovoltaic energy accounts for fifteen gigawatts of global energy, which is equivalent to fifteen large electric power plants. Also, the production of PV cells has increased by two thousand times over the past twenty years, and it is expected to continue to grow. Solar-thermal energy takes the thermal energy created by the sun and turns it into electricity. Although it only only produces as much energy as one large power plant, solar-thermal energy has many domestic uses. It can not only be used for electricity, but also for solar heating, which uses sunlight to heat up houses. Solar power has already proven to be a reliant source of energy, and it will only continue to improve in technology and

Solar power, or photovoltaics use light as a source of electricity. The photoelectric effect, discovered by Edmund Bequerel in 1839, shows that some materials have the ability to release electric current when subjected to light. Solar cells consist of semi conductors that are specially treated to create

Everything from the sun is a source or form of energy. Energy is considered, the ability or capacity to do work. This would mean, without the sun we are unable to fuel any of our biotic organisms, thus destroying their functions. Of course there are alternate ways of producing energy, however as the sun is our largest output of energy by far; the earth does not have the sufficient resources to survive without it. The sun gives life to plants and animals as well. Later on these plants and animals may turn into fossil fuels, acting as an alternate source of energy, or even using the plants themselves as sources of energy. The sun not only acts as an energy source itself, but indirectly creates other sources of energy as well. Think of it like a tree diagram. All sources of energy, branch off from the sun, without the sun there is no energy, thus halting all functions throughout the world. Energy is essential, and the sun again, being the main source of energy, is also essential for humans to continue living on earth. As a result, the sun too acts as an “engine” for energy on

“22.1 percent of the energy in sunlight into electricity”. According to Kevin Bullis from Technology Review “First Solar Cell Break Efficiency Record”. As we know solar energy is a renewable energy source but how does it work? (PV) cells turns sunlight into electricity. Then is converted into an altering current electricity. An electrical power then sends power to our lights and applications.

The energy the Earth receives from the sun, primarily as visible light and other forms of electromagnetic power. The term solar energy often refers to processes that use this energy to generate heat or electricity for human use. Just how does sunshine become electricity? Here 's an overview of the solar energy facts, the process, and the equipment that can help you generate your own clean, more affordable energy. The solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current electricity throughout the day. A device converts the DC electricity generated by the solar panels into the alternating current electricity. The AC electricity is sent from the inverter to your electrical panel to power your lights and appliances with solar energy. The electrical panel is often called a "breaker box." The utility meter measures your energy use. It actually goes backward when your system generates more power than you immediately need. This excess solar energy offsets the energy you use at night. Your business is still connected to the grid. You’ll need that power from the utility company at night, but don’t worry. The cost is offset by any

In August of 2003, the largest blackout in US history happened because of Ohio 's failure to trim trees away from power lines. As a result, more than 50 million people in the Northeast, Midwest, and Canada were out of power for days. While Ohio is going back and forth on it its laws dealing with solar power installation, our friends across the Canadian border have already shut down the last of their coal powered plants. The current US power grid is over 100 years old and due to its heavy use, is getting weaker every day. Blackouts, power imbalances, power interruptions, and changing voltage levels are all too common today, especially in the summer (Weeks). Fossil fuels like coal and oil pollute the world we live in. Ohio is among the many states where laws are being put in place for states requiring it 's energy to be obtained from alternative renewable sources. Solar energy is the best possible source, and Ohio should look to it for its future energy needs.
