For example, wood, wood chips, even garbage can be incinerated and the heat used to produce steam to heat office buildings, as in Charlottetown, Prince Edward Island. The Alberta Oil Sands produce petroleum in Canada. A continuation of the petroleum-making process over tens to hundreds of millions of years results in natural gas. In Canada, natural gas is produced at the Sable Offshore Energy Project off the coast of Nova Scotia - energy from nuclear disintegration Nuclear energy results from the spontaneous disintegration of radioactive substances that emit highly charged particles. This disintegration releases energy.
Water is always in motion.
It evaporates into the air in the form of water vapour. As warm air rises from a body of water it takes a lot of water vapour with it. Sooner or later this warm, water-laden air cools, and the water vapour turns into rain. The rain falls on the Earth, flows down creeks and rivers to lakes, and eventually is either evaporated again or returns to the oceans. This water cycle is repeated over and over again.
