Every day we rely on energy to provide us with electricity, hot water, and fuel for our cars. Most of this energy comes from fossil fuels, such as coal, oil, and natural gas. These are nonrenewable energy sources, which means that if we use them all up, we can never get more during our lifetime. Fossil fuels also contribute greatly to global climate change by releasing carbon dioxide into the air when they are burned.

Because fossil fuels can run out and are bad for the environment, it is important that we start switching to other energy sources, like renewable energy sources. These are energy sources that are constantly being replenished, such as sunlight, wind, and water. This means that we can use them as much as we want, and we do not have to worry about them running out. Additionally, renewable energy sources are usually much more environmentally friendly than fossil fuels. Overall, they release very few chemicals, like carbon dioxide, that can harm the environment.

Currently, less than ten percent of all the energy we use comes from renewable sources. So, you might be wondering, 'if renewable energy sources do not harm the environment and will not run out, then why are we not using them everywhere and all the time?' It is because many of them are currently expensive to harness, are inefficient, or have other disadvantages. For example, using energy from the wind might be great in an area that is really windy all year-round, but it wouldn't work so well in an area with very little wind.

$\Huge{Solar}$$\Huge{Energy}$

Solar energy, or energy from the sun, is harnessed using solar collectors. This collected energy can then be used to provide heat, light, or other forms of electricity.

Pros: Sunlight is free and readily available almost everywhere. Using it does not create any wastes or pollutants.

Cons: The technology needed to collect and use solar energy can be expensive. Sunlight can only be collected during the day when it is sunny

$\Huge{Wind}$$\Huge{Energy}$

Wind energy is just what it sounds like: energy that we get from the wind. Windmills have been used for hundreds of years to pump water from the ground. Today, we use large, tall wind turbines that use the wind to generate electricity. Many wind turbines are often placed together in wind farms in flat areas with strong winds.

Pros: Does not produce any waste or pollutants. It takes up little ground space.

Cons: Wind turbines can disturb or kill flying creatures, like birds and bats. Wind is not constant and reliable everywhere.

Answer 2

A renewable resource is a resource which can be used repeatedly and replaced naturally. Renewable energy never runs out, example: solar energy is powered by heat the sun and never runs out. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as paper and leather. It is also very healthy for the environment.

Gasoline, coal, natural gas, diesel, plastics and other fossil fuels are not renewable. They take millions of years to be made, and cannot be renewed in a human lifetime or even a nation's lifetime. Ways have been developed to make biodegradable plastic and bio diesel and other fuels from renewable resources such as corn, sugar cane, soybeans and canola. Mac
