    Many countries use fossil fuels like oil, natural gas, or coal to generate electricity,
  • 00:00:08
    but this process produces a lot of greenhouse gases, such as carbon dioxide, which are harmful to the Earth.
  • 00:00:18
    What can we do?
  • 00:00:20
    The best solution is using clean energies.
  • 00:00:24
    In this video, we are going to learn about clean energies.
  • 00:00:30
    Part 1 - Listen to a short talk about clean energy!
  • 00:00:36
    Clean, renewable energy sources are becoming more and more important as we work to reduce greenhouse gas emissions and fight climate change.
  • 00:00:47
    There are several main types of clean energy that are growing in use and popularity.
  • 00:00:54
    Solar energy is one of the most important sources of green energy. Solar powerplants get energy from the sun to generate electricity.
  • 00:01:05
    A powerplant is a place where electricity is produced. A solar powerplant is a place with a lot of solar panels.
  • 00:01:16
    Solar panels convert sunlight into electricity that can be used at homes, offices, and more.
  • 00:01:24
    Now, solar panels are cheaper than they were some years ago, and as a result, more people are using them.
  • 00:01:34
    Experts predict that solar power could provide 20% of US electricity by 2030, up from only about 5% in 2022.
  • 00:01:46
    Solar energy doesn't produce any air or water pollution, making it much better for the environment than burning fossil fuels.
  • 00:01:57
    We can also generate clean electricity by using wind. Large wind turbines are used to convert wind into electricity.
  • 00:02:06
    There are many wind farms on land and at sea to provide clean, renewable energy.
  • 00:02:15
    Denmark is the leading country in using wind power to generate energy. In 2022, more than half of Denmark's electricity production comes from wind farms.
  • 00:02:29
    Generating electricity by using water is another option.
  • 00:02:33
    Hydropower uses moving water - usually from a river behind a dam - to move turbines and generate electricity.
  • 00:02:45
    Hydropower is not a new technology and many countries in the world are using it.
  • 00:02:50
    It's important because it's a constant source of energy, providing around 16% of the world's electricity today.
  • 00:03:01
    It might be interesting to know that we can use the heat inside the Earth as a source of energy. It is called geothermal energy.
  • 00:03:11
    Geothermal energy uses the natural heat beneath the Earth's surface to produce heat and electricity.
  • 00:03:20
    Geothermal plants draw hot water from underground reservoirs to drive turbine generators.
  • 00:03:29
    Iceland is one of the world’s leading countries in the use of geothermal energy.
  • 00:03:35
    In 2020, more than 70% of the total energy used in Iceland came from geothermal sources.
  • 00:03:45
    Using clean renewable energy sources like these will reduce greenhouse gas emissions from electricity production.
  • 00:03:53
    Clean energy can also improve public health by reducing air pollution.
  • 00:04:00
    While fossil fuels will continue providing a share of our energy for some time, clean renewables must keep growing to create a better future for us.
  • 00:04:14
