What else can I help you with?
Is wind energy more efficient than hydroelectric energy?
Yes, but only because Hydroelectric generated electricity can be produced 24/7.
What type of energy is more efficient than fossil fuel energy?
renewable energy, for example solar energy, hydroelectric energy and Wind Energy.
Why is hydroelectric power more efficient than the use of coal or uranium?
Hydroelectric power is 100% efficient as there is no energy requirement to draw/start power production (outside of that to construct the materials of course). To start coal or uranium energy processes energy is required to start the process. These processes rely on heat from these energy sources to create steam which can run turbines which naturally lose energy released from these sources. Because not all of this energy is released in the form of thermal energy and because converting energy is intrinsically inefficient, these sources of power are currently less energy efficient. (actually hydroelectric plants are no more efficient than any other turbines, and possibly less than most highly efficient multi- stage compound condensing steam turbines. The efficiency is based upon how much of the energy passing through the turbine is converted to mechanical energy. Roughly 60% for the best designs.) Hydroelectric power has high start up costs, dam building [habitat flooding], and can only be built in specific areas (river valleys) as they take up vast quantities of space. ]
Does green electricity make more power than other methods?
No. Some forms of renewable energy (e.g. solar cells) are much less efficient than conventional energy sources. Modern coal and natural gas power plants are about as efficient as it is possible to make an energy source. Hydroelectric power plants are about the only renewable energy source with efficiency near coal and natural gas power plants.
Where does most renewable energy we use come from?
Most renewable energy comes from sources like solar, wind, hydroelectric, and biomass. Solar energy, in particular, has seen rapid growth as the technology becomes more efficient and cost-effective. Wind energy also contributes significantly, followed by hydroelectric power which has been a staple of renewable energy for many years.
Why should humans have more hydroelectric power?
Humans need more electricity, regardless of source. Hydroelectric and other renewable sources of energy are preferred to energy produced from the burning of fossil fuels.
Some argue that hydroelectric power should be used to generate more of the energy for the US Which argument could be used to dispute this idea?
Expanding hydroelectric power production can have negative environmental impacts such as disrupting aquatic ecosystems, displacing communities, and altering natural river flow. In addition, the construction of new hydroelectric plants requires substantial upfront capital investment and may not be the most cost-effective or efficient solution compared to other renewable energy sources like solar or wind power.
What alternative energy source is more efficient and sustainable than solar power?
Geothermal energy is considered more efficient and sustainable than solar power as it provides a consistent source of power without being dependent on weather conditions.
How is hydroelectric power and potential energy related?
Hydroelectric power is generated using the potential energy stored in water at a height. When water flows downhill through turbines, the gravitational potential energy is converted into mechanical energy to generate electricity. Therefore, the greater the height difference or potential energy of the water, the more electricity can be produced.
What state produces the most hydroelectric power?
When the water is falling from height. The more the falling speed, the greater the energy.
How does the amount of energy obtained from nuclear sources in 1990 compare with the amount obtained from moving water?
In 1990, more energy was obtained from moving water sources, such as hydroelectric power, compared to nuclear sources. Hydroelectric power was a more established and widely-used form of renewable energy at that time, while nuclear power faced public perception challenges.
What countries are 'energy independent'?
Some countries that are considered more energy independent include Norway, Canada, Brazil, and Australia. These countries have diverse energy sources such as oil, natural gas, hydroelectric power, and renewable energy that allow them to meet their energy needs domestically.
