The uneven solar radiation on the Earth's surface makes the atmosphere, water and hot air uneven. Half of the Earth's surface, at night, is obscured from receiving the sun's radiation and, moreover, solar radiation is closer to the equator than at the poles, so there's a difference. The difference in temperature and therefore the pressure difference between the equator and the poles as well as the air between the daytime and the night side of the moving Earth makes wind. The rotating Earth also contributes to vortexing and because the Earth's axis is tilted (relative to the plane formed by the Earth's orbit around the Sun), it also creates seasonal air currents. .Due to the effect of the Coriolis effect created from the rotation of the Earth's axis, the air going from the high pressure to the low pressure does not move braking but creates vortex winds with different vortices between the North. hemisphere and southern hemisphere. If viewed from space, in the Northern Hemisphere the air moves into a low pressure area anticlockwise and out of a high pressure area clockwise. On the Southern Hemisphere, the opposite trend.

In addition to the global factors on the wind is also affected by the terrain in each locality. Because water and soil have different heat capacity, during the day the soil heats up faster than water, making a difference in pressure and so there is wind blowing from the sea or lake to the mainland. At night the land cools faster than water and this effect happens in the opposite direction.

The sun is an abundant source of energy that humans can exploit in the very far future.In Vietnam, solar energy is also being exploited and developed, the most popular of which is solar heat. People use wind energy to supply electricity to the family and the whole city, thanks to the creativity of scientists. Another clean energy source is also promising and is being invested by many countries. exploited from ocean waves, this is a huge source of energy and long lasting enough to provide for mankind.
