Environment MattersRenewable & Non-Renewable Resources

Energy exists freely in nature.

Some of them exist infinitely (never run out, called RENEWABLE), the rest have finite amounts (they took millions of years to form, and will run out one day, called NON-RENEWABLE).

Sources can be renewable or non-renewable.

Renewable resources are natural resources, which are able to quickly replenish themselves and can be used again and again.

● Solar ● Geothermal● Wind ● Biomass● Water

Renewable Resources

These include:

What are some examples where you have seen renewable resources being used today?

Water, wind, sun and biomass (vegetation) are all available naturally and were not formed.

Renewable energy can be converted to electricity, which is stored and transported to our homes for use.

Examples of how Renewable Energy is

used

Solar energy is the sun's rays reaching the earth. This energy can be turned into heat and electricity.

Solar Energy

How many ways can you think of that the sun's energy is used directly today?

• Energy from the sun is free. • The sun’s energy is clean,

meaning it causes no pollution.

Advantages

Disadvantages

• The amount of sunlight that arrives on the Earth varies depending on location, time of day, time of year, and weather conditions.

• Because the sun doesn’t deliver that much energy to any one place at one time, a large surface area is required to collect energy at a useful rate.

Examples of how Renewable Energy is used

Wind Energy

Wind is simply air in motion.

The moving air (wind) has huge amounts of kinetic energy, and this can be transferred into electrical energy using wind turbines.Wind turbines are usually sited on high hills and mountain ridges to take advantage of the prevailing winds.

Advantages

• Wind energy is free• Does not cause green house

gases or other pollutants.• Although wind turbines are

very tall, each takes up only a small plot of land.

Disadvantages

• The strength of the wind is not constant, so wind turbines do not produce the same amount of electricity all the time.

• Wind turbines are noisy• Some people don’t like how

they look.

Non-Renewable Energy

Non-renewable resources are limited because they are an energy resource that is not replaced or is replaced only very slowly by natural processes.

For example: oil will eventually run out one day!Most non-renewable resources are fossil fuels.

Some examples are: Oil Coal Copper Diamonds Natural gas Iron Ore Minerals Gold Silver platinum

But not all are!e.g. Uranium

These won’t exist anymore once we have used them all up!

How are Fossil Fuels Formed?

Fossil fuels are formed from buried remains of plants and animals that lived millions of years ago.

…but the rate of their production is extremely slow, much slower than the rate at which we use them.

Examples of how they produce Energy

PetroleumOil, or petroleum, is used to create fuels, such as gasoline, diesel and jet fuel. It is also used in the manufacturing of plastics and industrial chemicals.

The environmental impacts of mining oil include threats to waterways, plants and wildlife due to oil spills and increased infrastructure in natural areas. The impacts of oil combustion include air pollution, smog and increased greenhouse gas emissions.

Nuclear Energy

Nuclear power requires uranium. It does not create air pollution like fossil fuels. It produces radioactive waste, which must be disposed of and which can cause problems for humans and ecosystems for thousands of years. Accidents and leaks from nuclear power plants can have catastrophic effects on the entire planet.

Advantages & Disadvantages

Why should we keep using non-renewable sources?

• Easy access• Cheaper.• Makes a lot more energy efficiently

Why should we stop or reduce our usage of non-renewable sources?• Except for Nuclear power, all of them are contributing

green house gases, which cause global warming.• Mining for resources can damage and destroy the

land - leaves land barren, can result in the sinking or collapse of land, pollutes water sources, pollutes the air, affects the health of miners, etc.

• Once we completely use nonrenewable resources, we won't have them anymore

What do you think will happen when these non-renewable resources will eventually run

out?

Pros Cons

Quantity is limitless, it will never run out

Difficult to set up

The energy is free to use

Expensive to set up

Environment friendly

Not always efficient because need large amounts which is not always available.

Pros Cons

Cheap to use Will run out some day

Easy to use Causing serious environmental changes

Efficient – only require a small amount to produce a large amount of power

Releases toxic gases which are contributing to global warming

Prices will rise in the future as supplies run out

Renewable Energy

Non-Renewable Energy

Summary of Pros & Cons

So we need to find more renewable, sustainable ways of

generating energy.

Class Quiz & Discussion

What is the difference between renewable and non-renewable resources?

What were some examples of renewable resources?What were some examples of non-renewable resources?What are some ways we can start using more renewable energy resources now?

It is important because we need to take better care of Earth’s creations as well as

survival in the future.If video doesn’t work, go to the following link to watch: http://www.youtube.com/watch?v=MjCcmSdraRI
