Answer:

Explanation:
Answer:
energy can never be created nor be destroyed and is always reversable according to laws of Conservation of energy and thus if it is wasted much then there will be no energy to be converted also , the only incredible source of energy is sun even in it also it is converting hydrogen to helium in the nuclear fussion and once the hydrogen is totally converted into helium It will die
after death iT will either be a dwarf star or might be possible it became black hole but since it has used only 25% of hydrogen so this phenomenon will take place after 5 billion years
capturing solar energy is not a simple work since sun's radiation is a scattered resource and should be attracted toward something to be collected thus energy saving is an important task to do
