It's Got Staying Power
In a Flash
What is renewable energy?
Renewable energy is any natural resource that can replace itself quickly and dependably.
Renewable energy sources are abundant, sustainable, and environmentally-friendly – making them a great choice for us humans and our planet!
Unlike fossil fuels, renewable energy sources won't ever run out, as they are constantly replenished no matter how much we use. So while supplies of fossil fuels like coal and oil will eventually be depleted, renewable energy sources will always be there.
Types of Renewable Energy
The energy in wind can be harnessed by large blades on wind turbines, which use it to generate electricity for residential and commercial purposes.Let's go! >
Solar energy comes from the sun. It's the primary source of energy for all living things on Earth, and can also be converted into electricity through solar cells.Let's go! >
Biomass is an organic matter, such as wood, crops, seaweed, and animal waste. It gets its energy from the sun and can be used to produce electricity.Let's go! >
Hydropower energy comes from the force of moving water. Hydropower plants use dams to capture water energy and convert it to electricity.Let's go! >
Geothermal energy comes from the heat generated by the Earth, such as volcanoes or geysers. It can be used to produce electricity, and provide heat and hot water.Let's go! >
What's the Big Deal About
Using renewable energy sources has challenges as well as benefits.
Renewable energy is important for a bunch of different reasons, such as:
- It reduces global warming emissions, which makes for a safer, greener environment
- Renewable energy sources reduce air and water pollution, so are better for our health
- As there is more work involved in harnessing renewable energy, the industry creates more employment opportunities and other economic benefits
- Renewable energy helps to keep energy prices stable
- Being renewable, we have an abundant supply of these energy sources – they're unlikely to ever run out, even in a billion years from now!
The Good and Bad of
Renewable Energy Pros:
- Stable energy prices
- Continual source of energy
- Low cost operation
- Low global warming emissions
Renewable Energy Cons:
- Vulnerable to weather and other climate events
- Limited supply of energy
- High cost of development
- Require a large space to set up
- Not available in all areas
