Question

Best economic method to harvest the solar energy is

• A. Solar cell
• B. Energy plantation
• C. Cultivation of sugar cane then energy obtain by burning it
• D. Solar cooker

Answer 1

The correct option is B Energy plantation

The economics of terrestrial growth of vegetation for its energy content is far more favourable than other more technically sophisticated methods of large-scale solar energy conversion. The most traditional is to use the ability of plants to convert the suns energy into fuel molecules; this is cheap, deployable at scale, and provides the energy in easily storable form, but its not very efficient and so needs a lot of land.
