The Great Energy Debate

What are renewable resources?

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale. Some examples are solar, wind, hydroelectric, biomass, geothermal. This is a positive life cycle assessment, this is a key indicator of resources sustainability.

What are nonrenewable resource?

A resource of economic value that can not be replaced by natural means on a level equal to its consumption. Most fossil fuels such as oil, natural gas, and coal are considered nonrenewable resources because they where formed billions of years ago.

Hydropower!!!

Why is hydropower a good energy resource?

Hydropower is a good energy resource because its clean and dose not contribute to global warming and climate change.

Also hydropower does pollute the air with pollution. Hydropower also has a lot to do with the water cycle. Using the water cycle it is a efficient way to produce electricity. Hydropower is also renewable so it can be replaced in a short period of time, it is also inexpensive.

Another reason hydropower is a great resource is because it is a renewable energy. This resource could be replaced naturally and can be used again.

Hydropower, or also known as waterpower is power derived from the energy of falling water and running water, which may be harnessed for useful purposes. Is also renewable it can be replaced.

Disadvantages

1. Dams are extremely expensive to build and must be built to a very high standard.

2. The high cost of dam construction means that they must operate for many decades to become profitable.

3. The flooding of large areas of land means that the natural environment is destroyed.

4. People living in villages and towns that are in the valley to be flooded must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydropower schemes can go ahead.

5. The building of large dams can cause serious geological damage. For example, the building of the Hoover Dam in the USA triggered a number of earthquakes and has depressed the earth’s surface at its location.

Advantages

1. Once a dam is constructed, electricity can be produced at a constant rate.

2. If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved for use another time when electricity demand is high.

3. Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades.

4. The lake that forms behind the dam can be used for water sports and leisure / pleasure activities. Often large dams become tourist attractions in their own right.

5. The lake's water can be used for irrigation purposes.

FACTS ABOUT HYDROPOWER!!

Hydropower is the nation’s most available, reliable, affordable and sustainable energy source. Requiring only the power of moving water – rivers, streams and ocean tides– hydropower is also domestic and sustainable. Free from a dependence on volatile fuel prices, much of the money invested in hydropower stays in America and expanding hydro capacity would create hundreds of thousands of U.S. jobs.

Hydropower is keeping the lights on in every region of the country. It is America’s largest source of clean electricity, accounting for 52 percent of all renewable energy generation in the United States, and with the right policies, it has significant room to grow.

Hydropower has been a reliable source of power in the United States for over 100 years. That proven reliability benefits the national electric grid in a number of ways, from supporting other renewable energy sources to stabilizing the network to storing electricity for later use.

Solar

What is solar energy?

Solar energy is the most abundant and the most cost effective energy source. Solar energy is derived from the sun. This energy is not only clean it is also a renewable resource.

What are the advantages and disadvantages of solar energy?

Advantages

1. Solar energy does not pollute the air with pollution

2. There is a lot of areas with sun and open land

Disadvantages

1. The amount of solar energy that reaches the earths surface varies in different areas

2. Only 15-20% efficient costly to start up                                                                                                     

Wind

What is wind energy?

Wind energy is one of the cleanest sources of energy because it is naturally generated. Wind energy is created through the conversion of wind. Wind power also uses wind turbines to produce electricity and energy. Lastly wind energy is renewable so it can be replaced in a short period of time.

Advantages

1. Does not pollute the air or water

2. Can be used in remote areas

3. Low cost than other resources

Disadvantages

1. Wind turbines can be noisy and ugly

2.Can disrupt wild life

3. Only generate energy when wind is blowing

Geothermal

What is geothermal energy?

Geothermal energy comes from the heat within the earth. People mainly use geothermal for electricity and heating their homes. Many people use geothermal all around the earth compared to other energy. Since geothermal is renewable it can be replaced in a short period of time.

What are the advantages and disadvantages of geothermal energy?

Advantages

1. Limitless source of energy

2. Power plants requires little amount of land

Disadvantages

1. Only available in places with hotspots

2. Waste can damage soil  

Biomass

What is biomass energy?

Biomass is an organic matter; wood, crops, seaweed, and animal waste. That can all be used as a energy source. Biomass is the oldest energy resource after the sun. People use this energy source to heat their homes and cook their food. Biomass is also renewable.


What are the advantages and disadvantages to biomass energy?

Advantages

1. Biomass is cleaner

2. Is a renewable resource

Disadvantages

1. Requires large areas

2. Produces smoke

Coal

What is coal energy?

Coal is a form of energy that is natural and comes directly from the earth. Coal is a fossil fuel which means it is nonrenewable. The earth only has a finite supply of coal energy. That also means that one day it will run out.

What are the advantages and disadvantages to coal energy?

Advantages

1. Easy to transport

2. widely available
