Which surface has a higher albedo: a White roof top or a concrete sidewalk?
white roof top
Which country produces the most amount of renewable energy?
Canada or Sweden
How does Geothermal energy work?
This process typically involves drilling wells into geothermal reservoirs to access hot water and steam. The steam spins the turbines, connected to generators which converts the mechanical energy into electrical energy. After passing through the turbines, the steam is cooled and condensed back into water, which can often be re-injected into the reservoir to maintain the cycle
Define Albedo
An object's ability to reflect sun radiation back into space
Who receives most benefits from extracting natural resources for renewable technologies?
Global North, mining companies, countries and communities that are not found where the resources are mined.
What is the average lifespan of a wind turbine?
20-25 years
How many countries have committed to net zero GHGs?
50% or 107 coutnries
What is the difference between wave and tidal energy?
Wave energy convertors are placed at the surface and rely on crashing waves for kinetic energy
Whereas tidal energy convertors are anchored to the seafloor and rely on currents and tides created by the gravitational pull from the moon for kinetic energy.
