i dont know you tell me
Our civilization uses enormous amounts of power. We have run through about 50% of about 1 million years of oil in just 50 years (very roughly). About 50% is still in the ground. Our recovery methods keep improving and there is still unfound oil in the ground, but our needs keep growing, as for example the growing economies of India and China. Our in ground oil has been estimated at a mere 17 years. Solar, wind, water, earth heat, etc. all help, but there is going to be a big gap, hence the need for atomic energy.
The percentage of energy imported from other countries has generally increased over the last 50 years due to global energy demand growth, economic factors, and geopolitical developments. This trend has led to concerns about energy security and supply diversification.
Fossil fuels are deacyed plant matter from millions of years ago. The source of energy in the fuel is the carbon. When plants grow they use carbon dioxide from the atmosphere and they separate the carbon from the oxygen by photosynthesis, which uses the Sun's energy directly because separating the atoms of carbon and oxygen requires energy. The carbon is used to make plant tissues while the oxygen is mostly emitted as a waste product. But when the fuel is burned, the carbon is recombined with oxygen to produce carbon dioxide, and the formation of the chemical bonds beween the atoms releases energy as heat. This energy is the energy that was originally absorbed from the Sun all those millions of years ago. So the Sun is the original source of energy for fossil fuels, but the energy was taken 50-100 million years ago and the amount being burned now produces too much CO2 for the Earth to deal with properly.
Electricity , as a secondary source of energy, is easy to transport and easy to be converted at end energy use point to energy the form needed (as in lighting, heating, industry, transportation, etc.). Electricity by itself as secondary energy source is environmentally clean secondary energy source. Pollution caused by its production depends on the type of the used primary source (coal, oil, gas, nuclear energy, wind, etc.) However, electricity is usually produced in thermal power plants at efficiency less than 50%. So, it is expensive high grade secondary energy source.
Hair straighteners typically consume around 20-50 watts of energy when in use. The exact amount can vary based on the brand and model of the straightener. It's important to turn off and unplug the straightener when not in use to save energy.
Iowa's main source of energy is nuclear power. There are over 50 nuclear stations called mps (nuclear power station). And has only had 50 accidents in teh last ten years!
Future cars may use bio fuels or solar energy and may be run on water power
Nuclear fusion is not a viable source of energy at this point. The technical difficulties in maintaining confinement are enormous and have not yet been overcome. There are projects ongoing to attempt to resolve the issues, but we are at least 10 to 20 years away from anything, and more probably 50 to 100 years away from commercial use of nuclear fusion.
Coal - about 50 percent of total
For electricity it is still coal, at about 50 percent. For transport it is oil.
Right now, except for the Sun, fusion is not a viable source of energy. We do not expect commercial production from fusion energy for another 50 to 100 years, if then. The technological obstacles are presently insurmountable, primarily due to problems with containment, but we are working on them.
Coal
This is difficult to decide I think. It has been available for 50 years now - does that make it conventional? It is a well established and reliable energy source.
Non-renewable energy sources are those that drain the fossil reserves. The most important non-renewable energy source on Earth is coal. If something is not done to make the switch to clean or green energy, the coal supply is not expected to last for more than 40 to 50 years.
she is 50. online source from 2000 she was 40
Probably, but it depends on fusion being successful, and it will take another 50 years to find out
50-40 thousand years ago
