Types of Energy
This type of energy comes from the sun and can be converted into electricity.
Solar power
Burning fossil fuels releases this gas, which contributes to global warming.
Carbon dioxide
This device stores energy and is commonly used in electric cars and portable electronics.
Battery
This interconnected system delivers electricity from power plants to homes and businesses.
The grid
Renewable energy sources are naturally replenished, while this type of energy takes millions of years to form.
This renewable energy source relies on moving air to generate electricity.
Wind energy
The total amount of greenhouse gases emitted by an individual, company, or country is known as this.
Carbon footprint
Solar panels convert sunlight into electricity using this type of technology.
Photovoltaic technology
Energy efficiency is measured by comparing the amount of energy input to the amount of useful _____.
output
This term refers to how well energy is converted into useful work.
Efficiency
A dam is often used to generate this type of renewable energy.
Unlike fossil fuels, renewable energy sources do not release large amounts of this harmful byproduct.
Greenhouse gases
Hydroelectric power stations often use this large structure to control water flow.
Countries investing heavily in solar and wind energy often need this kind of backup power source for when the weather is unfavorable.
Fossil fuels or batteries
Solar panels work best in areas with a lot of this.
Sunlight
This non-renewable energy source comes from the remains of ancient plants and animals.
Fossil fuels
Some critics argue that wind and solar power are unreliable because they depend on these two natural conditions.
Wind and Sunlight
A key challenge for wind and solar energy is improving the _____ of energy storage systems.
One of the biggest advantages of nuclear energy is that it produces a large amount of electricity with a small amount of this.
fuel
Many countries are switching to renewable energy to reduce their dependence on this type of imported resource.
This type of energy is produced when atoms are split in a controlled reaction.
Coal fired power plants
Unlike traditional power plants, small-scale solar and wind installations allow individuals to become these independent energy producers.
Prosumers
In many places, outdated infrastructure makes it difficult to integrate renewable energy into this large-scale distribution system.
The grid
Hydroelectric dams can generate a lot of power, but they also have a negative environmental impact by disrupting these natural features.
Rivers or ecosystems
