Resources

All resources in nature divide into renewable and non-renewable. All resources in nature divide into renewable and non-renewable. Renewable resources can be replenished through natural processes or be replaced through biological processes. But even renewable resources are not unlimited. Non-renewable resources cannot be replaced

Energy

Energy sources Renewable : Solar energy Wind energy Tidal energy Hydropower Biomass Geothermal energy Non-renewable: Coal Crude oil and petroleum Natural gas Nuclear power

Non-renewable energy sources Fossil fuels have a high percentage of carbon. That is why burning fuels we also release carbon dioxide, which contributes to global warming. Nuclear power does not Nuclear power does not pollute the air. However, there are many risks that a small mistake at power plants can cause a catastrophe.

Fossil fuels and nuclear power are quite dangerous for our environment. Fossil fuels and nuclear power are quite dangerous for our environment. Our global use of energy increases every year. The challenging question is how we can satisfy our demands. One way is using renewable energies. They are more distributed and have minimal amount of drawbacks.

Water One of the cheapest alternative energy source is water To get electricity from water people build hydropower plants China, Canada, Brazil, the United States, and Russia are the largest producers of hydropower.

Hydropower plants

Advantages of Hydropower It’s a clean fuel source and doesn’t pollute the air Hydroelectric power is a domestic source of energy, so each state can produce its own energy The energy generated through hydropower relies on the water cycle. It is a renewable power source, more reliable and affordable than fossil fuels Some hydropower facilities can quickly go from zero power to maximum output. They provide essential back-up power during electricity disruptions
