Energy is the power we use for transportation, for heat and light in our homes and for the manufacture of all kinds of products. There are two sources of energy: renewable and nonrenewable energy.
<span>
Nonrenewable Sources of Energy</span>Most of the energy we use comes from fossil fuels, such as coal, natural gas and petroleum. Uranium is another nonrenewable source, but it is not a fossil fuel. Uranium is converted to a fuel and used in nuclear power plants. Once these natural resources are used up, they are gone forever.
Renewable Sources of Energy
Renewable sources of energy can be used over and over again. Renewable resources include solar energy, wind, geothermal energy, biomass and hydropower. They generate much less pollution, both in gathering and production, than nonrenewable sources.
Hope this helps xox :)
The scientists' conclusions are most likely unreliable because <u>he asked the wrong set of people for his survey.</u> By definition, environmentalists are those people who are inclined to believing that humans are entirely responsible for creating biological foot prints all over the Earth.

Red, green, and brown algae have accessory photosynthetic plastids containing different pigments than the chloroplasts.
<span>It is known that chlorophyll absorbs red light and reflects green. That's why plants containing chlorophyll are green. </span>At a depth of the sea where these algae live, there is no red light but different. Red, green, and brown algae have other pigments that can absorb that different light and which allow these algae to maximum use sunlight.
