Which scource of energy would be the most economical and safest for the community to pursue?
Radiant energy is the safest energy for people and the environment.
What is a example of a renewable source?
four examples of renewable energy are: -wind -sun -water -solar power two examples of non-renewable resources are: -oil -natural gas I am only in grade 5 so that is pretty much all that i can think of BUT THESE ANSWERS ARE CORRECT SO IF YOU NEED THIS INFORMATION IT IS SAFE AND REAL TO FOLLOW. thank you for reading! :D
Which of the following can be called non-conventional source of energy?
The non-conventional sources of energy are: 1. Wind Energy advantages- non-polluting; low cost production of electricity once setup; safe and clean disadvantages- noise pollution; wind mills costly to setup; disturbs radio and T.V. reception; harmful to birds. 2. Solar Energy advantages- inexhaustible; non-polluting disadvantages- expensive; diffused source, so gets wasted. 3. Tidal Energy advantages- non-polluting; inexhaustible disadvantages- destroys wildlife habitat; difficult to harness 4. Nuclear energy advantages- Emits large amount of energy disadvantages- generates radioactive waste; expensive 5. Bio Gas advantages- low cost; easy to operate; makes use of bio waste disadvantages- causes green house effect 6. Geothermal Energy advantages- clean Eco friendly and always available disadvantages- located far away from cities and so costly to transport the electricity
Which is the best description of an alternative energy resource?
One that doesn't work cheaply or well enough to be a prime energy source. No, that's not the answer your teacher is looking for... this is approved "green" answer what they want from you: Alternative energy sources are those which are renewable, not based on the consumption of a fixed resource like coal, uranium, or petroleum. Alternatives are clean and safe, with low environmental impact, unlike dirty coal and dangerous nuclear power. But don't tell your teacher that wind turbines kill birds and bats by the ton, that tidal power destroys fish, that geothermal power creates earthquakes, or that most solar panels have dangerous heavy metals in them. That's not the indoctrination they are after.
Why aren't renewable energy resources widely used?
AnswerThey are more expensive than other energy sources.AnswerAll energy sources have considerations of cost, availability, and attainability (which is itself determined by technological and non-technological limits). Solar power is 'free', but the devices to collect it are expensive compared to the power they deliver, thereby making solar power expensive. There are also a limited number of locations where it can be collected. Hydroelectric power is 'free', and the devices to collect it are cheap, but the number of locations at which it can be collected are few in number (most are already being used). Geothermal power is 'free', and collecting it is moderately priced, but there are technological constraints to how well the energy can be collected, and there are few places where it can be collected. Wind power is 'free', and not free. The devices used to collect it are moderately expensive, but wind farms need more traditional power sources (typically fossil fuels) as back-ups, which increases the costs and reduces the efficiency. Like solar, there are also a limited number of places where wind farms are practical. Agri-power or bio-fuels must be grown, and are not 'free'. While converting agricultural products into fuel is rather simple, it is using food for fuel, which creates a competition between feeding people and feeding cars.== There's a documentary film called "Who Killed the Electric Car?". It's about a company that started selling electric cars, until the US Government, oil companies and other powerful people conspired to put a stop to it. (But I haven't seen it myself.) == The typical middle class US home grid tied solar installation can cost between $25000 and $40000 out of pocket installed. The federal tax credit is limited to a lifetime max of some $2000. Some state and local tax credits are available but not as many as could be out there. The typical home wind turbine runs about $25000 to $35000 installed and you have to get a tower permit to install it which are denied in many suburban settings. There is also no legislation in place to ban home owner associations from having in their bylaws that you can't put up a wind tower or install solar cells on your house if one of your neighbors doesn't like the look of them. - This is of Jan 2009 and hopefully will change. So - it's almost pure cost. Most people in the US do not stay in a home long enough to save the money in utility bills to pay for such a pricy installation. Substantial improvements in solar cell technology will bring these costs down a little over time and hopefully the federal tax credit will be raised to further fill the gap. It is a matter of being able to afford your environmental convictions.
What is term used to describe renewable ecologically safe sources of energy?
Eco Energy
Term used to describe renewable ecologically safe sources energy?
alternative energy
What are some alternative energy sources that are safe for out environment and also renewable?
wind. solar. hydro.
Is alternative energy renewable ecologically safe source of energy?
Renewable energy doesn't get used up, in the way that coal and oil do. It is still there the next day, such as sunshine; wind power; water power from rivers and oceans; and geothermal power, which uses the heat deep below the surface of the earth. They are also called the Alternative energy sources.
What is the term used to describe renewable ecologically safe source of energy?
1.source energy. 2.alternative energy.
What are three advantages an disadvantages of hydrogen energy?
renewable energy source non-poluting very safe and in-expensive large amounts can be stored up and used later
What are some describing words for hydroelectric energy?
Some words to describe hydroelectricity are reliable, safe, renewable, clean, feasible, and efficient.
What do chemical and renewable energy engineers do?
Chemical engineers and renewable energy engineers may work together or isolation. Renewable energy engineers are involved in design, operation, maintainence and harnessing energy from tidal energy, solar energy, geothermal energy,wind energy etc. Chemical engineers are involved in design, operation, maintainence of plants for producing valuable chemicals, materials, or generating cleaner energy, environmentally safe systems and evaluate processes and products. Chemical engineers can become renewable energy engineers when they get involved with fuel cells, next generation hydrogen technologies, green manufacturing, nuclear energy, bio-fuels,geothermal energy etc etc.
Which scource of energy would be the most economical and safest for the community to pursue?
Radiant energy is the safest energy for people and the environment.
What is the most environmentally safe sort of energy?
Solar and wind energy is the most safe. Of the renewable energies, nuclear can produce nuclear waste and go critical, while hydroelectric power can displace many acres of land. Wind and solar energy produce no waste, do not pollutes, and do not displace.
What are the advantages of renewable and non-renewable energy sources?
One advantage is it would help to save fossil fuels 2nd advantage: Because of using the renewable resource, we can renew it again and again . . . . 3rd advantage: It will be forever and can renew in such a short time.
What are some important advantages of using renewable resources instead of non renewable resources?
Advantages of Non-Renewable EnergyBecause non-renewable energies seem abundant, like oil, gas and coal, some experts believe if channeled correctly, our supplies will be safe for future generations. Non-renewable energy sources include oil and petroleum products, gasoline, diesel fuel, and propane, natural gas, coal, and uranium used for nuclear energy. Some environmentalists include our forests, trees, and plant life as a non-renewable energy source as well especially due to the deforestation of our forests.One advantage of non-renewable energies is that right now, they seem widely available and affordable. Oil and diesel are still good choices for powering vehicles. They are cost effective and much easier to produce and use. Non-renewable energy also has market value where a supplier or manufacturer makes money and pays workers enhancing economies.Although governments struggle with fair trade practices, many countries have a non-renewable energy source which can used as a bargaining tool to help their economy stay afloat.
