Renewable Energy Sources
This energy source uses sunlight to generate electricity.
What is solar energy?
This element is key to nuclear fission in power plants.
What is uranium?
This greenhouse gas is the primary by-product of burning fossil fuels.
What is carbon dioxide?
This type of bulb is more energy-efficient than traditional incandescent bulbs.
What is an LED bulb?
This term refers to the process of capturing and storing carbon dioxide emissions underground.
What is carbon capture and storage (CCS)?
The flow of this resource is used to generate hydroelectric power.
What is water?
This fossil fuel is the main component of natural gas.
What is methane?
This term refers to the increase in Earth's average temperature due to greenhouse gas emissions.
What is global warming?
Insulating a home helps conserve energy by reducing this.
What is heat loss?
This energy storage method uses surplus electricity to pump water to a higher elevation, releasing it to generate power when demand is high.
What is pumped hydroelectric storage?
This renewable energy harnesses the power of moving air.
What is wind energy?
This non-renewable energy source is formed from the remains of ancient marine organisms.
What is oil?
This term describes the damage caused to ecosystems during coal mining.
What is habitat destruction?
Using this type of window reduces energy loss by providing better insulation than single-pane windows.
What are double-glazed windows?
The process of splitting water molecules to produce hydrogen as a clean fuel is called this.
What is electrolysis?
This form of energy relies on heat from beneath the Earth's surface.
What is geothermal energy?
This sedimentary rock is used to produce coal energy.
What is bituminous coal?
Nuclear power generation produces this type of long-lived waste that poses storage challenges.
What is radioactive waste?
Modern car designs improve fuel efficiency by using lightweight materials and optimizing this feature to reduce air resistance.
What is aerodynamics?
This concept describes a future where energy needs are met entirely through renewable resources.
What is a net-zero energy system?
The process of capturing energy from plant material is known as this.
What is biomass energy?
This term refers to the time it takes for half the atoms in a radioactive material to decay.
What is a half-life?
This energy extraction technique has been linked to increased seismic activity in certain areas.
What is fracking?
This term refers to the measure of how easily heat is transferred through a material, playing a key role in designing energy-efficient buildings.
What is the heat transfer coefficient?
This term describes a future energy system where hydrogen serves as a primary fuel for transportation, electricity, and heating, replacing fossil fuels.
What is the hydrogen economy?
