Energy Resources Advantages And Disadvantages

1. What is a disadvantage of using wind as a method of generating electricity?

It creates more air polllution

It produces hazardous waste

Wind speed is not always constant (blowing steady)

Wind is a nonrenewable resource

Wind speed not being constant is a disadvantage of using wind as a method of generating electricity because it affects the reliability and consistency of power generation. In order to generate electricity from wind, a certain minimum wind speed is required. If the wind speed is too low or too high, the turbines may not be able to produce electricity efficiently or may need to be shut down altogether. This variability in wind speed makes it challenging to rely solely on wind power for consistent electricity generation.

2. One advantage of using biomass as a renewable energy source is that biomass –

Is a less concentrated energy source, making it less efficient

Is more expensive than fossil fuels

Release pollution into the air when burned

Decreases organic waste create from plants and animals

Biomass is a renewable energy source that decreases organic waste created from plants and animals. This means that instead of allowing this waste to accumulate and potentially become a problem, biomass energy utilizes it as a valuable resource. By converting organic waste into energy, biomass helps to reduce the amount of waste that would otherwise end up in landfills or contribute to pollution. This not only helps to manage waste effectively but also contributes to a more sustainable and cleaner energy system.

3. An advantage of burning coal to generate power for electricity is that coal is -

Inexpensive to mine and transport

Available in limited supply

Found in a few places in the United States

Harmful to the environment

Coal is advantageous for generating power because it is inexpensive to mine and transport. This means that the cost of extracting coal from mines and transporting it to power plants is relatively low compared to other energy sources. This affordability makes coal a cost-effective option for electricity generation, especially in regions where it is readily available. However, it is important to note that while coal may be inexpensive to mine and transport, it is harmful to the environment due to its high carbon emissions and contribution to air pollution.

4. Hydroelectric energy is produced by moving water. Water from rivers held behind large dams flows over turbines, which drive generators to produce electricity. What is the disadvantage of using hydroelectricity over other methods?

There are problems with disposing of hazardous waste

Building dams can destroy wildlife and enviroments

This method only uses natural resources and energy

There are problems with pollution of land areas around water

Building dams can destroy wildlife and environments.

Explanation

Building dams can destroy wildlife and environments.

5. What do geothermal and solar energy have in common?

Neither produce greenhouse gases (air pollution)

Sunlight is needed for both to produce electricity

Both are nonrenewable resources

Neither requires expensive machinery to produce

Geothermal and solar energy have in common that neither produce greenhouse gases (air pollution). Geothermal energy harnesses the heat from the Earth's core, while solar energy converts sunlight into electricity. Both methods are considered clean and environmentally friendly, as they do not release harmful emissions that contribute to climate change or air pollution.
