The three sources of energy include,
Solar energy
Wind energy
Water and geothermal.
Energy is termed as the capacity of physical system to do work. It exists as kinetic or mechanical energy, light potential energy, electrical and heat.
Source of energy can be classified as renewable and non-renewable.
The renewable is derived from natural processes which replenished constantly, for example, solar energy, biomass, ocean, hydropower and wind.
The solar energy it is sustainable to mean that it does not run out but it is maintained reason being that sun shines every day.
A good advantage of solar is that it is natural and available in plenty, and non-pollution. Wind energy helps to turn the blades of windmills as it turns shaft to where they are attached.

<span>B. Animals must switch between ectotherm and endotherm methods.
</span>The hypothalamus in the brain, is responsible for monitoring the body temperature. The hypothalamus causes the body to react differently when the body is too hot or if the temperature gets too cold. <span>The normal body temperature is 37'. The hypothalamus triggers the receptors such as sweat glands and body hair muscles in the body.The sweat glands open up when the body is too hot and secrets sweat until the temperature is regulated again. Similarly in cold conditions the body hair muscles pull the hair upright because standing hair absorbs more heat until the falling body temperature returns to normal.</span>
"severe weather conditions" are the only things than can be reasonably well predicted with the help of science. Of course the accuracy of these predictions varies greatly.
