How long have we known we can create energy from the sun?

    If you include creating fire as creating energy, humans began using the sun’s rays to light fires by concentrating the beam through a magnifying glass since the 7th century BC. But I presume you mean more traditional solar power, in which case the answer is for about 230 years. In the mid 1770s Swiss physicist Horace de Saussure constructed the first solar collector which could be used to cook food.
