Biology · Secondary 3 · Hard · Causes of global warming
A country currently generates most of its electricity by burning coal. The government plans to replace half of the coal power stations with solar farms. How will this change affect the country’s contribution to global warming?
- It will decrease because less coal is burned, so less carbon dioxide is released.
- It will increase because solar panels absorb more heat from the Sun.
- It will stay the same because electricity use does not affect carbon dioxide levels.
- It will increase because coal power stations remove carbon dioxide from the air.
