What is one way to reduce the use of nonrenewable energy resources?

By increasing the use of renewable energy sources!

Explanation:

To satisfy the need for power in (whatever country you live in) you need to have a certain quota of power. This is typically achieved by the use of oil and natural gasses. You can also achieve it though by using thermal energy as well as solar energy (Solar Panels), and wind, kinetic, and water. (Windmills and Watermills). These are quite difficult to make and cost a lot of money to produce and kept running smoothly. So to cut back on cost we just use oil/natural gasses. But to answer your question, we need more renewable energy to make nonrenewable energy less used!

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
