Renewable Energy
What is the main component of a solar cell that converts sunlight into electricity?
Photovoltaic (PV) material.
What is the definition of non-renewable energy?
Energy derived from sources that are finite and cannot be replenished in a reasonable amount of time, such as fossil fuels like coal, oil, and natural gas.
What is the most abundant greenhouse gas in the Earth's atmosphere?
The most abundant greenhouse gas in the Earth's atmosphere is carbon dioxide.
This scientific law states that in any energy transfer, the total amount of energy remains constant.

What is the name of the international treaty aimed at reducing greenhouse gas emissions and mitigating climate change?
The treaty is called the Paris Agreement.
This type of energy transfer occurs when energy is transferred through the motion of an object, such as a ball rolling down a hill.
What is mechanical energy transfer?
The rate of work performed in a system

What is the name of the process that involves injecting water and chemicals into shale rock formations to release natural gas deposits?
Hydraulic fracturing or "fracking".
What is the term for actions taken to prepare for and respond to the impacts of climate change, such as sea level rise and more frequent extreme weather events?
The term is climate adaptation.
This concept describes the transfer of heat energy from one part of a fluid to another part of the same fluid, due to differences in temperature and density.
What is thermal conduction?

What is the name of the type of coal that has the highest carbon content and is the most energy-dense?
Anthracite.
Which greenhouse gas has the highest global warming potential, meaning it traps more heat in the atmosphere than other gases?
The greenhouse gas with the highest global warming potential is sulphur hexafluoride (SF6).
This type of energy transfer occurs when a substance undergoes a phase change, such as from a liquid to a gas or a solid to a liquid.
