The Different Types of Natural Energy
Author: James Bratley
Tidal energy is fast becoming a popular choice for many governments as a result of more efficient technologies, which take advantage of the energy behind incoming tides. The disadvantage of tidal energy is expense and engineering capabilities.
Related to the tidal theory, but on a much smaller scale, is a method we are beginning to see used more widely in a number of countries, especially the U.K. This alternative method uses small propeller blades under running streams. This is becoming a popular choice for renewable energy in the countryside. This technology has been around for hundreds of years in the form of watermills.
Now we shall move on to wind. On-shore and off-shore wind turbines harness their power from wind energy. Off-shore turbines are generally more reliable, as the wind out at sea is fairly constant and of a significant average strength. On-shore turbines however, can still provide the same capacity as off-shore turbines, yet finding these perfect spots is tricky, and a wind farm proposal is usually met with anger from locals.
Geothermal (ground source) energy has been making a huge presence in countries such as Iceland, Sweden, Norway, and more recently the U.K. The geothermal energy under your feet is enough to heat water to a significant degree, and this can save you money on your heating and electricity bills, depending how you wish to use this energy.
Finally, the most common natural energy source used across the globe today is solar energy. The sun contains huge amounts of energy, and it is right there above our heads. No drilling is needed, and this energy can be used just about anywhere. It is one of the most versatile energy solutions available, and with the help of a solar panel, can heat your water, or provide you with electricity.

Biomass energy
Geothermal energy
Hydrogen
Hydropower
Ocean energy
Solar energy
Wind energy
The main renewable sources of energy to generate electricity are:
1.Hydro-power (use of water from rivers, dams, tides and ocean waves)
2.Wind energy (using wind turbines)
3.Solar power (using the power of the sun to heat water or produce electricity)
4.Geothermal (using the heat deep under the earth’s crust)
5.Ocean Thermal (using surface heat and deep cold water)
6.Biofuel (producing ethanol from organic material like switch-grass, corn and sugar cane husks)
The main categories are:
Wind power
Wave power
Solar power
Geothermal
Biofuels
Geoexchange
Each of these has one or more variants, so see the link below for lots of great detail and pictures.
Hydroelectric is renewable, and cheaper than coal. Unfortunately, there is a limited supply of rivers.
I believe wind is about double the price of coal for a centralized plant. But only certain places are good for wind.
Natural gas, a fossil fuel, is comparable to wind. Same for diesel powered generation of electricity.
Photovoltaic (solar) is twice again as expensive as wind for a centralized plant. It used to be 3x, but panel prices have come down considerably.
But here’s the catch. If you’re an individual homeowner, the economics are different. You will pay retail for electricity, and even solar is comparable or cheaper in many areas. Electricity may cost 5 cents a kWh to generate, but by the time it gets distributed and taxed, it costs the homeowner 15 cents. That’s why we see homeowners putting up solar, but no big centralized solar plants.
solar-will last for atleast 500 million years
wind-will last as the earth exists
geothermal-will last as the earth exists
hydro-how ever we prevent greenhouse effect.
tidal-again as long as earth exists and rotates due to the sun
bio fuel-as long animals excrete.
nuclear fission.but gives out equal amount of pollutants.
How many different types of renewable/clean energy sources are there and what are they?
I have recently seen a new solar thermal generator in mexico which leeds me to wonder what other ones dont i know of.

A few questions about Renewable Energy Resources?
I just wanted peoples answers and opinions for these questions. I am doing a test for renewable energy resources. I am actually a science professor for Harvard.I just have a few questions about renewable resources that I have been wondering out of curiosity. Well here they are. : )
1. What are the different types of renewable resources?
2. What are some of the advantages?
3. What are some of the disadvantages?
4. How does it impact our environment?
5. How does the conservation issue impact these alternative
sources of energy?
6. How does the Recycle-Reduce-Reuse policy apply to
these energy sources?
Can u list some different types of renewable energy sources?
im writtting a essay i have windmill energy and solar power
what is the cost of renewable energy?
What is the cost of the different types of renewable energy?
How does the price compare to that of fossil fuels?
