Names of sustainable energy resources?

Question

any source of energy that is renewable or atleast stay till human race exist. it should not be polluting the environment. please enlist a few 4 me. its 4 an action research project.

Answer 1

I attended the Focus the Nation at Sierra College on 1-31-08. The event was the 2% Solution, a 2% reduction over 40 years to solve GW. Oil is a nonrenewable resource and we are running out-but not soon - $30 Gal for gas. The 2% Solution is ok for the USA for a 10 year plan to cut 20%. But over those 10 years, we have to be building renewable energy and about that time, we can cut an additional 20%. This should get us from importing any oil. We must have a pollution surcharge where we pay the real price (health effects, GW and cleanup) for oil, NG, coal, cigarettes, Cooling Towers, Cars, trains and airplanes. Humans have to put some of this nonrenewable into renewable energy like small hydro-electric dams, concentrating solar power plants, wind and wave machines, nuks, and geothermal. With the peak of oil in the 1970’s, peak NG in the 1990’s, having mined cheep coal, the peak of ocean fishing in the 1980’s, and the peak of uranium in the 1990’s, humans must stop procrastinating and make real changes to keep earth sustainable including in the energy debate, finance and regulation.

Many of mankind’s advancements cause earth surface to warm, destroy the ozone layer, kill off endanger species, heat cities, and in some way cause more dramatic destruction.  Blacktop and buildings (roads, roofs and parking lots-heat cities), deforestation (air pollution, soil erosion), duststorms (increase hurricanes and cyclones, cause lung diseases), fires (cause pollution, mud slides, and deforestation), refrigerants (like CFC's) and solvents (including benzene destroy the ozone layer raising skin cancer rates) and plastics; cars, airplanes, ships and most electricity production (causes pollution including raised CO2 levels and increased lung and other diseases); these human problems we must fix to keep life on earth sustainable! Humans have destroyed half of the wetlands, cut down nearly half of the rain forest, and advance on the earths grasslands while advancing desertification which increases duststorms.

The result is:  change is on the way, we just do not know what changes (where and when). Look beyond the hype, beyond the weather, beyond a quarterly report and beyond today. President Bush has made a choice of energy (ethanol) over food and feeding the starving people around the world; this is a choice China has rejected. The fact is Bush wants to buy your food to send to starving people since our grain is not available. Now what USA Presidential candidate is give you the facts so you can make an educated decision?

Over the next 90 years carbon dioxide is projected to skyrocket as human’s burn more fossil fuels. The problem is, the oil will be gone in less than 30 years at present rates of consumption without projected increases and shortages. We have to come up with what will take its place. Again we have to cleanup our mess. One of the big problems we have is at some time Yellowstone will blow its top again, as the magma move closer to the surface, creating a nuk winter. After that we will not have to worry about the destruction of the ozone layer, global warming or pollution.

But with that we must understand we have never seen what is now happening before. CO2 has never lead to temperature change, but temperature change has led to increases in CO2. The models have to be made as we go along with current evidence! But again adding a small amount of CO2 to the atmosphere enlarges the earths sun collection causing warming; increase water in the atmosphere and it forms clouds cooling earth but sometimes causing flooding. Even natural events are warming earth and causing destruction. The sun has an increased magnetic field causing increases in earthquakes (more destruction), volcanoes (wow, great destruction), and sun spots. Lighting produces ozone near the surface (raising air pollution levels). The USA Mayor's have taken a stand and I believe are on the right track, we can have control and can have economic growth. The sun is available to produce energy, bring light to buildings and makes most of human’s fresh water. Composting is the answer to desertification. New dams are the answer to fresh water storage, energy and cooling earth by evaporation, we need many small ones all over (California needs 100 by 2012 and has not even started).

Remember knowledge is power and this information is very powerful. Humans have 50 trillion dollars worth of stuff that runs on cheep oil, natural gas, or coal. We need 20 Trillion Dollars worth of renewable energy over the next 10 years if we are to avoid a world wide depression (and right now ethanol does not count)!

That is why I founded CoolingEarth.org, a geoengineering web sight where you can learn more about earth, the atmosphere, and how to sustain life on earth’s surface.

Answer 2

which research re???Ne ways.... according to me it should be the solar resorce as the human race'll end by the time the oceans'll flood but the sun'll remain lnger than that so my answer goes to the solar resource and after that the human resource as till humans are there human resource will be there and according to me by the rate we are using resources today after a few years human resouce will be the only otion left!

Answer 3

In absolute terms except sun energy none of the energy sources are pollution free.

For your project:

Hydropower is a non -polluting energy source besides solar, tidal, wind etc. energy sources.

thnks

Answer 4

wind, solar, geothermal, wave, hydroelectric, and nuclear.

Nuclear is not polluting because there is no net generation of radiation. It's taken from a dilute form(uranium) and concentrated. There is a problem with storage of the waste, but it's managable. I think France gets about 1/2 its energy from nuclear.

Answer 5

Plasmagasifiction not to be confused with incineration not the same thing.  It uses a plasma arc tourch to break soild waste from landfills into its basic elements.  It is contained in a low to no oxygen enviroment allowing harmful elements to be removed.  It produces syngas for electricity and slag for roadbeds and other construction.  There is a plant being built in Port St Lucie, Florida that will process 1500 tons of trash a day and one in New Orleans processing 3000 tons per day.

Answer 6

tidal /sea energy to run electricity generators.

solar/sun energy

thermal/hot springs energy  (used in Scandinavian countries)

wind
