What is geothermal energy?
Turning off lights when you leave a room is an example of this.
What is energy conservation?
One major effect of climate change is the rise of these.

What is energy efficiency?
Access to electricity in rural areas can improve this sector (like schools or clinics).
What is education/healthcare?
A person walking instead of driving to reduce emissions is reducing this.
What is a carbon footprint?
This is the process of converting sunlight directly into electricity.
What is photovoltaics?
Which NON-fossil-fuel energy source is clean but not considered renewable?
What is nuclear energy?
These invisible gaps in windows or doors often waste energy by doing this.
What is heat or air escaping?
The process of organizing cities with walkability and green transport is called this.
What is sustainable urban planning?
A home built to use almost no outside energy is called this type of home.
What is a net-zero energy home?
