Photovoltaics And Their Role In The Future Of Renewable Energy
Author: karlopaolo24
One of the largest forms of renewable energy available is solar. In order to convert the radiation from the sun to electric power, photovoltaic cells are required. The photovoltaic effect is the process by which the radiation is converted. Read on about photovoltaics and the advancement of solar energy.
You can characterize solar technology by how it can be captured. It is captured in one of two ways, either passively without the use of any electrical or mechanical device like a solarium. It is also captured actively which would use some type of electrical or mechanical equipment for assistance. A photovoltaic cell can be used either way.
In one year, the amount of solar energy that falls to the surface of the earth is so enormous that it will surpass by double the amount of non-renewable energy sources of coal, oil, natural gas, and mined uranium on the earth. The levels of solar power that can be captured in the world are different, depending on the area that it is being captured in. Areas closer to the equator will capture more solar power.
The first application for the photovoltaic was its use in powering orbiting satellites and spacecraft. Now they are used most often for power generation in grid connections. A photovoltaic module (solar cell) is made up of many photovoltaic cells and the modules produce direct current (DC) which must then be converted to alternating current (AC).
Photovoltaic cells or solar panels were expensive to install, but now, with new government incentive programs from various governments worldwide things have changed. Use of solar energy is being widely encouraged. The most recent events have shown that we need to be using solar power now more than we ever have before. Solar panels have also decreased in price just over a period of time in the past few years.
When photovoltaic cells were first introduced to the public, they had menial uses, such as calculators and gadgets, but now, we are testing roadway lighting systems. The presence of them can be seen in street lamps, parking meters, and phones. There are power stations in different areas of the world in operation with photovoltaic panels. There is no doubt that the need for them will grow with the need for renewable energy.

About the Author
Photovoltaic cells are used to take the energy from the sun and converting them into electric power. If you want it done right, , then you should get a PV installer to do it for you.
Look into the degree and course requirements. It’s probably a year or two before you need to make that choice. The best renewable energy industries may not be big, and might not even exist yet. Get the solid background in the understanding of science and the engineering discipline and see where it leads you.
Future Career: Renewable Energy?
Hey everyone,
I have to decide over the course of the next fortnight which degree I want to study at QUT, Australia.
I have been awarded Deans Scholars Acelerated Honours Program (Science), which is just a fast tracked Bachelor of Applied Science Degree. Also, I have been awarded Vice Chancellors Scholarship, which just gives me the financial support to get through any degree I choose to study.
My other preferences, include Bach Science/ Mathematics, Bach Engineering (Electrical)/ Mathematics, Bach Engineering, Bach Science.
I want to get into Renewable Energy design. Im just really not sure what field, an Australian university graduate in the field would be best to head towards. Are there any engineers out there who work for big renewable energy industries, do they design the big hydro/wind farms, or the solar towers? I just really dont know what is best for me, Science Degree or Engineering Degree.
Anyone care to help?
To many people think that we need massive projects to make a change its not true.
Think of it this way to save at least 20% less electricity around the home TODAY if you changed your lighting to CFLs and turned everything off standby – pretty simple.
Do a few other things around the home save another 30% without spending to much. After you have done that you have reduced your power bills by half and paid for your original investments
Its not in the future its now!
future of renewable energy in the world?
Solar Energy requires the area to be free of trees so the sun can get through to the collector. The collector can block the sun robbing plant life of valuable nutrients. This is very limiting to it’s usability, however as new technology emerges we may see less of this impact and it may become more feasible.
Wind energy requires wind which sometimes we have, sometimes we do not. Again the usability is limited.
Hydro power: well Hoover Dam is already built, and the ecosystem there has already been messed up, and replaced with a new one. It can stay, but I hope we don’t go destroying anymore ecosystems for this power source.
Geothermal heat, there is still a lot of learning to do here. In some locations where experiments have been done the area has cooled down. I can’t be sure that we fully understand what effect the cooling of these geothermal hot spots will have on the environment, and surrounding ecosystems. The creation of mass amounts of steam might turn a desert into a wetlands, or rain forest if done on a large enough scale.
Biofuels, everyone thinks they are the wave of the future. If we do not produce enough foods to feed the starving now, then why take away from our food source to move cars?
Methane, I believe this might prove to be one of the most viable renewable energy sources we have. Most animal’s feces give off this gas (including humans) and a lot of it is just released into the environment. A lot of cow and hog farmers are building smaller power plants on their farms, and selling the power to the power company. It’s probably feasible for cities to attempt this at municipal waste treatment facilities too. I don’t think it would be feasible for the average joe to attempt this in his back yard though.
How many fossil fuels does Wisconsin use up in a day?
I am doing a science project on which is the best renewable future energy source for Wisconsin. Either solar energy, wind power, or methane gas. I need to know percentages of energy used up by the state, the number of fossil fuels being used up compared to all other states, and I need to know Wisconsin’s total sunlight and wind (mph) amount in a year. I need links to websites. So can you please help me?
The EIA (U.S. Energy Information Administration) collects, analyzes, and disseminates independent and impartial energy information.
NERL (National Renewable Energy Laboratory) is the facility of the U.S. Department of Energy (DOE) for renewable energy and energy efficiency research, development and deployment.
The first link below is about Wisconsin.
There are separate sections for energy production and energy consumption.
what do you think is the future impact of renewable energy?
I’m sure it will be hydrogen from water, because there is no pollution.
Making renewable energy sources stronger?
Is it possible that in the future, renewable energy source as solar, wind, geothermal, etc., can be made into a major energy source (at least 20% of the total energy make-up)?
How? (I’m don’t really know much about the newer technologies included in producing energy)
