Solar power is one of the best-known sources of renewable energy, but it is still only responsible for 3 percent of global electricity. What's keeping it back and how can it further develop?

Swapping out glass panels for transparent solar modules, and harnessing the energy from wavelengths of light not used during photosynthesis, could help turn greenhouses into self-sufficient solar power plants.

Sunflowers have been expertly capturing the power of the sun for millennia, and now modern science is catching up.

Can I have some solar power with my soy milk, please?
