NON-RENEWABLE ENERGY SOURCES

RENEWABLE ENERGY SOURCES

VS

• A renewable resource is one that can regenerate quickly and is replaceable,
• They can be used again an again and will never run out.
• They are also environment friendly.

• They will eventually run out one day and there is a limited amount of them
• They cause a lot of pollution
• A non-renewable resource is one that cannot be resupplied by natural resources.

Fossil fuels – coal, gas and oil

• Fossil fuels are non-renewable sources of energy and will eventually run out one day. They are burned to generate useful energy and are made up of chemical energy. Fossil fuel power plants generate heat by burning coal or oil, which is then used to generate steam, which drives turbines, which then generate electricity. An advanatge of using fossil fuels is that they can create a large amount of electricity in one place and can easily transport oil and gas through pipelines. Some disadvantages of this is that they pollute the environment and if its used incorrectly they can be dangerous.

Nuclear fuel – uranium and plutonium

• Nuclear fuels are non-renewable souces. Heat is produced by nuclear processes, which is utilised to generate steam, turn turbines, and power generators. Some advantages of using nucleur fuel i s that they dont produce gases whcih pollute the environment and doesnt contribute to global warming. It is very cheap and envolves low transportation and mining. Some disadvantages are that the disposal of this fuel is very hard and costs a lot of money. It cannot react quickly to changes in electricity.

Biofuel

• Any fuel that is created from biomass and is plant or algae material is referrred to as biofuel. In boilers or furnaces, dry, combustible biomasses such as wood pellets are burned. As a result, water boils and steam is created, which powers a turbine to generate electricity. A disadvantage of biofuels is hat they cost very high and it causes food hortage. It also cloggs engines. Some advantages is that they make the most of our planet's carbon cycle to help lower the carbon footprint of transportation and other industries.

Wind power

• Windpower is a renewable energy source that generates electricity using the power of the wind. The wind rotates a turbine's blades around a rotor, which turns a generator, which generates electricity. It has the advantages of being a clean source, as well as being cost-effective and long-lasting. It is also a cost-effective use of land in comparison to other options. Some negatives include the fact that it is not very reliable and can be costly to set up, as well as the fact that people who live near it are not safe. It also generates a lot of noise, which can be disturbing.

Hydroelectricity

• Hydroelectricity, often known as hydroelectric power, is electricity generated by water. It is a renewable source of energy. Hydropower systems use a turbine to transform potential energy into kinetic energy, which powers a generator to generate electricity. Hydropower provides flood control, irrigation support, and clean drinking water in addition to energy generation. Hydropower is a cost-effective option. In comparison to other energy sources, hydropower provides low-cost electricity and long-term durability.The environmental impact of hydroelectric energy is perhaps its most important. It causes people to be displaced and is pricey.

tidal energy

• Tidal energy is generated via a turbine that functions similarly to a wind turbine, with blades turning 12 to 18 times per minute depending on tide strength. The turbine is linked to a gearbox, which drives a generator, which generates power.Tides are easy to anticipate and low-cost to manage. It is a dependable and a renewable energy source. Other renewable energy sources have a lower energy density. It doesn't emit any greenhouse gases or waste. The impact on animals and plants living near tidal stations is one of the drawbacks. There are few good locations for building barrages, and they also disrupt the migratory of live species in the water

Solar energy

• Solar energy is both renewable and "green" in the sense that it has no negative environmental consequences. Solar energy captures the sun's energy and converts it to power for your home or business in a quiet and efficient manner. Solar energy is pollution-free and does not emit greenhouse gases after installation. Dependence on foreign oil and fossil fuels is reduced. Even cloudy days provide some power from renewable clean energy that is available every day of the year. The material and installation costs are significant at first. It also takes up a lot of room and has been linked to pollution.

how the Sun can be also be used directly in heating systems (solar panels)

Sol

Solar water heating systems, also referred to as solar thermal systems, use solar energy to heat water for storage in a hot water cylinder or thermal store. Since the number of available solar energy tends to vary throughout the year, a solar water heating system will not provide all of the hot water needed. Solar collectors, which are panels or tubes that collect solar radiation, are used in solar water heating systems. The infrared part of visible light is converted to heat by the solar collectors. They're made up of a mixture of water and glycol. This fluid is circulated in a circuit that includes the hot water cylinder.

Step 1

Step 2

Even though we still use gas more we use much more renewable energy which means that we are protecting the planet.

Here we can see that we used natural gas more and not much of the others.

When will fossil fuels run out?We are expected to run out of fossil fuels by the end of this century. Oil has a 50-year shelf life, natural gas has a 53-year shelf life, and coal has a 114-year shelf life. However, because renewable energy is not widely used, depleting our stocks can hasten the process.If we continue to burn fossil fuels at our current rate, all of our fossil fuel reserves are expected to be depleted by 2060.

other ways we use fossil fuels

We use fossil fuels for our cars, power our businesses, and keep the lights on in our homes. We also use gas for our stoves to cook
