Answering Fan Questions About Photons, Fire & Gravity Waves

Solar Power

Solar energy is a primary cosmic energy source, powering various forms of renewable energy on Earth. Neil deGrasse Tyson explains that solar power is essentially the energy we harness directly from the sun, and it is renewable until the sun exhausts its energy 1. He also highlights that even tidal energy, often associated with the moon, has a component that originates from the sun, known as Luni Solar Tides 2. Neil poses the question, "Can it be traced back to the sun or does it stem from a different origin?" emphasizing the sun's role in Earth's energy systems 3.

   

Tidal & Geothermal

Tidal and geothermal energies are explored as viable renewable energy sources. Harrison Greenbaum describes geothermal energy as heat from Earth's mantle, which can be harnessed for sustainable energy, as seen in Iceland's use of geothermal power to heat streets 4. He also discusses the challenge of storing solar energy, suggesting innovative solutions like converting solar power into potential energy by lifting weights 5. Neil adds that tidal energy, while primarily lunar, also has solar contributions, illustrating the interconnectedness of Earth's energy sources 6.
