The image below shows a group of wind turbines, which can be used to produce electrical energy.
Several transfers of energy must occur to produce this electrical energy. First, an uneven energy transfer of energy to Earth's atmosphere produces wind energy. As the wind rotates the blades of a turbine, energy is transferred to the turbine. This transferred energy then turns generators inside the turbine to produce electrical energy.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
