1. What is Solar Energy? - Definition, Pros & Cons
Learn about solar energy and how charged particles from the sun travel to Earth to provide heat and light. Explore solar energy as a direct and indirect energy source and examine the pros and cons of harvesting solar energy for other uses.
2. What Are Solar Panels? - Photovoltaic Solar Cells and Solar Thermal Electric Generation
How do devices take advantage of the sun's abundant energy? Learn about photovoltaic solar cells and solar thermal electric generation and how these technologies can be used to convert solar energy into heat and electricity.
3. Biomass for Renewable Energy: Pros and Cons
Biomass is organic material that can be used to generate heat, electricity, and even fuel. In this lesson, you will learn about the advantages of this abundant and renewable energy source as well as the disadvantages.
4. Wind Energy: Pros and Cons
Wind energy is a renewable form of energy that involves harnessing the natural energy of the wind. Learn how wind is used to generate electricity and the pros and cons of this energy source.
5. Hydropower: Pros and Cons
Hydropower is power generated from moving water. Learn how this energy from water can be harnessed by hydropower plants to generate electricity as well as the pros and cons of this renewable energy source.
6. Geothermal Energy: Advantages and Disadvantages
Geothermal energy is heat energy that is stored within the earth. Learn the methods being used to tap into this thermal energy to heat buildings and generate electricity as well as the advantages and disadvantages of this renewable energy source.
7. Tidal Energy: Advantages and Disadvantages
The tides move a massive amount of water, and the energy from this moving water, known as tidal energy, can be captured and converted into electricity. Learn how tidal energy works and the advantages and disadvantages of this energy source.
8. Energy Conservation and Energy Efficiency: Examples and Differences
Saving energy is an important topic, but energy conservation and energy efficiency are not the same thing. Learn what the difference is and some examples of both energy conservation and energy efficiency.
9. Conserving Energy at Home: How to Be More Energy Efficient
Are you wondering how to make your home more energy efficient? Follow these measures to conserve energy, prevent energy loss, and make your home more comfortable, all while saving money.
10. Solar Energy: Understanding Active and Passive Solar Heating
Solar energy is the energy we harness from the sun. We can use this energy to heat our homes. Learn about the design elements needed for passive solar heating and the equipment needed for active solar heating.
11. What is Biomass Energy?
It's common these days to see and hear a lot about alternative energies in the media. The threat of global warming is becoming worse, so scientists are looking to other sources for our energy needs. This lesson answers your burning questions about biomass energy.
12. What Is Biomass? - Definition & Explanation
In this lesson, you'll learn what ecologists use to quantify the amount of matter in an ecological community. This often relates to the amount of energy being produced by various parts of that community.
