Renewables & Solar Thermal

Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Renewable energy is also called “clean energy” or “green power”, because it doesn’t pollute the air or the water.

Gasoline, coal, natural gas, diesel, plastics and other things that come from fossil fuels are not renewable. The problem with fossil fuels is that they are finite and they generate pollution and global warming gases causing the climate crisis.

That is why we need to stop using them and replace them with renewables!

Solar Thermal Collector


Solar thermal energy

People have used the sun as a heat source for thousands of years.
Today, we can put solar collectors for heating water and air in our homes. If you’ve seen a house with big black solar thermal collectors on the roof, that family is using solar energy.

Solar thermal technology is:

  • Efficient, because it can catch sunshine and use most of it to warm up water or space. Solar thermal energy is one of the most efficient renewable technologies out there!
  • Mature, because it’s a technology that has been around for many years now, and engineers understand it well and keep improving it constantly.
  • Easy! You don’t need very complex materials or knowledge to build your own solar thermal collector. With Our Solar Town, we will teach you how!
