Answer to Question #193943 in Electrical Engineering for Gta

Question

A: Describe four renewable and four non-renewable energy sources, stating advantages and disadvantages of each system

 

B: Using the information from Task 4A above, justify the use of different energy sources, include a non-renewable source and renewable source, to provide a nation’s electricity supply. Use your own reasoning and/or other resources like, parliamentary reports, Greenpeace opinions, local opposition groups, national and global economics to support your justification.

 

The future of different methods and fuels, life span of equipment and actual fuels, cost of fuel production, hazards and environmental impact should be included.

Answer 1

Non-renewable energy

Coal, natural gas, nuclear energy and oil.

Fossil fuels are made up of oil, natural gas, and coal. Fossil fuels were produced over millions of years in the Earth's interior from dead plants and animals, hence the moniker "fossil" fuels. They're found in rock and sediment layers underneath the earth. The plant and animal carcasses were transformed into crude oil by a combination of pressure and heat.

Crude oil is a liquid fossil fuel that is mostly used to make gasoline and diesel fuel for automobiles, as well as polymers. It is pumped out of wells and is located in rocks underneath the Earth's surface.

Coal is a type of solid fossil fuel that may be used to heat homes and power facilities. It can be discovered buried behind layers of dirt in ancient marshes. Coal cannot be extracted like crude oil or natural gas because it is solid; it must be dug out from the ground.

Nuclear energy comes from radioactive elements, mainly uranium, which is extracted from mined ore and then refined into fuel.

Natural gas is frequently utilized in households for cooking and heating. It is largely made up of methane and can be discovered near oil resources underneath the Earth's surface. Natural gas may be extracted using the same wells that are used to produce crude oil.

Advantages

Nonrenewable resources are inexpensive and simple to utilize.

A tiny quantity of nuclear energy may be used to generate a significant quantity of electricity.

Non-renewable resources face little or no competition.

Disadvantages

1.They emit carbon dioxide into the atmosphere, which contributes to global warming and climate change.

Renewable energy

1. Solar energy
2. Wind energy
3. Hydro energy
4. Geothermal energy

Solar energy

The quantity of solar energy that reaches the earth's surface in one hour is enough to meet the planet's whole annual energy needs. Although it appears to be an ideal renewable energy source, the quantity of solar energy we can utilize depends on the time of day, the season of the year, and our geographic location.

Wind energy

Turbines are used to drive generators, which subsequently send power into the National Grid, allowing wind energy to be harnessed. Despite the availability of household or "off-grid" generating solutions, not every property is appropriate for a household wind turbine. On our wind power page, you can learn more about wind energy.

Hydro energy

A big reservoir may be utilized to create a regulated flow of water that will drive a turbine and generate power by erecting a dam or barrier. This energy source (particularly if it's tidal rather than river) is frequently more dependable than solar or wind power, and it also allows electricity to be stored for use when demand peaks.

Geothermal energy

Geothermal energy may be utilized to heat houses or create power by utilizing the natural heat underneath the earth's surface.

Advantages

Renewable energy sources will never run out.

The amount of maintenance required is reduced.

Renewable energy is cost-effective.

There are various health and environmental advantages to renewable energy.

Disadvantages

Higher upfront cost

Storage capabilities

Intermittency

(b)

Renewable and non- renewable energy are all very fundamental in the world .Example crude oil plays a major role in the economy of a country and the world at large. Apart from that it also plays an important role in the use of machinery like cars and heavy machines despite its very many disadvantages.
