The greenhouse effect keeps Earth warm and keeps us alive.
Greenhouse effect: The warming of Earth's surface and above, caused by greenhouse gases (ex: carbon dioxide) that trap heat and energy from the sun.
~ The greenhouse effect may come out as being bad and harmful, but only too much of the greenhouse effect is bad. ~ How can people reduce the amount of carbon released, and still get the energy they need at home and at work?
Why is solar energy so important?
~ While fossil fuels contribute to climate change and the ongoing greenhouse effect, solar energy/panels produce energy in a cleaner way.
Understanding more about climate change.
~ Apart from maintaining Earth's climate by using solar energy, people are able to understand more about climate change.
~ We can learn more about what is causing climate change by learning about the solutions for preventing it. For example, if you're learning about solar energy, you may come across new points about climate change and ways to solve it.
~ Solar panels using photovoltaic cells: a photovoltaic cell group creates a solar panel which converts sunlight into electricity. Commonly used on rooftops.
~ Solar thermal technology: the sun's light and heat allow water to turn hot or steam that then spins a turbine which is connected to a generator.
~ Passive solar heating: allowing sunlight to come through (windows) to heat up an area instead of using heaters.
