Renewable Energy Sources:
This renewable energy source converts sunlight into electricity using photovoltaic cells.
What is solar power
This household item is recommended to be replaced with LED versions to save energy.
What is lightbulb?
The unit of energy commonly used in physics, symbolized by "J."
What is a joule?
This gas is the most significant contributor to the greenhouse effect and global warming.
What is carbon dioxide (CO₂)?
This household appliance, essential for food storage, has become more energy-efficient with modern technology.
What is a refrigerator?
This type of renewable energy is generated by capturing the heat stored beneath the Earth's surface.
What is geothermal energy?
Lowering this device in your home by just 1 degree can save up to 3% on heating costs.
What is the thermostat?
This law states that energy cannot be created or destroyed, only transformed.
What is the Law of Conservation of Energy?
This layer in the atmosphere helps protect the Earth from harmful ultraviolet radiation.
What is the ozone layer?
This type of light bulb is known for being more energy-efficient and lasting longer than incandescent bulbs.
What is an LED bulb?
The process of converting moving water into energy is called this.
What is hydroelectric power?
This practice involves turning off lights and unplugging devices when they are not in use.
What is energy conservation?
this is the form of energy stored in bonds between atoms in molecules.
What is chemical energy?
These areas, often tropical, are known as Earth's "lungs" because they absorb CO₂ and produce oxygen.
What are rainforests?
This type of modern thermostat can learn your habits to help save on heating and cooling energy.
What is a smart thermostat?
This type of biofuel is made primarily from corn and sugarcane and can be used in place of gasoline.
What is ethanol?
This type of water heating system can reduce energy consumption by using the sun instead of electricity.
What is a solar water heater?
When a nuclear reactor generates power, it splits the nucleus of atoms in this process.
What is nuclear fission?
This type of farming practice involves growing different crops in succession to maintain soil health.
What is crop rotation?
This type of vehicle uses a combination of gasoline and electricity to reduce fuel consumption.
What is a hybrid vehicle?
These large, white structures with rotating blades are used to harness energy from wind.
What are wind turbines?
The U.S. Environmental Protection Agency’s voluntary program to help individuals and organizations save money and protect the climate.
What is ENERGY STAR?
This energy transformation occurs when a wind turbine converts kinetic energy into this form of energy.
What is electrical energy?
These small particles in the atmosphere can reflect sunlight and are a form of air pollution.
What are aerosols?
This measure represents the efficiency of a machine or appliance, given as the ratio of useful output to total input energy.
What is energy efficiency?
