Seawater Energy
What are the instruments placed to create energy in the sea called?
tidal generators
What are the instruments placed to obtain wind energy called?
wind turbines
What is the name of the instrument used to store energy?
Battery/Batteries
Which country uses the most fossil energy?
United States
Which country uses the most tidal energy?
Britain
Which country uses the most wind energy?

How are fossil fuels extracted?
Fossil fuels are extracted from the Earth through processes like drilling for oil, mining for coal, or extracting natural gas from underground reservoirs.
What are the two main physical energies used?
Kinetic and potential energy
What energy is kinetic energy transformed into?
mechanical energy and then electrical energy
What is the most common semiconductor material in panels?
Silicon
How fossil fuels are formed?
Over millions of years, organic material like plants and marine organisms decomposed and accumulated in sedimentary layers, forming fossil fuels.
What causes tides?
Tides are caused primarily by the gravitational pull of the Moon and, to a lesser extent, the Sun on the Earth. This phenomenon causes periodic movements of rise and fall of water level in the oceans.
What physical energy is captured by wind turbines?
Kinetic energy
How does the photovoltaic effect of the panels work?
When sunlight hits the solar cells, it excites electrons in the semiconductor material, creating an electric current. This is known as the photovoltaic effect.
What is the name of the action that is done with this energy and how does it work?
When these fossil fuels are burned, typically in power plants or engines, they release energy in the form of heat. This process is known as combustion.
Describe how Seawater energy works
Seawater energy takes advantage of the movement of the tides to generate electricity. Devices are installed in areas with strong tides that capture the kinetic or potential energy of the water, activating turbines and producing electricity.
Describe how wind energy works
Wind energy is produced when the wind rotates the blades of a wind turbine, generating electricity through a mechanical and electromagnetic process.
Describe how solar energy works
solar energy works by converting sunlight into electricity using photovoltaic cells, providing a clean and renewable energy source.
Describe how fossil energy works
fossil energy works by extracting stored energy from ancient organic matter, releasing it through combustion, and converting the resulting heat into electricity for various applications.
