i need to identify 2 sources of renewable energy and explain why each is available indefinitely?

Answer 1

These include Solar, Hydroelectric, Wind, Biomass and Geothermal.

Solar Energy: this refers to the energy released through the use of solar panels.

Hydroelectric: As the consumption of electricity increased, hydropower came into the forefront. This saw the rise of hydroelectric power plants near cities to supplement the need for electricity.

Wind: Wind has been powering seacrafts since some time now.Windmills have also been used extensively in agriculture.

Biomass: the stored energy from plants that is converted into energy that can be used by man, is called as Biomass. Hence, burning wood is also an activity that produces biomass.

Geothermal: this refers to the energy generated by the heat that is already present on the planet, near the surface.

The advantage of these renewable energy sources is that they are inexhaustible and cause hardly any pollution. On the flipside, they are generating energy from these sources gets costly and hard to maintain.

Answer 2

None are available indefinitely. And the question should be potentially renewable energy.

The reason its not indefinitely as sooner or later the sun will burn out and wind patterns will sease to exist. With biomass if trees are not replanted or atleast allowed to regrow they cannot be renewable.

Now there are several potentially renewable energy sources.

Solar power is one, as the sun always shines through and this can be captured in solar panels to convert into energy that we can use.

Wind power is another source although these turbines must be placed in windy areas. Also this is not a consistant energy source as there is some down time, with different wind patterns and what not.

Hydroelectric dams is a consistant enenergy source that is renewable as long as the water flows.

Biomass such as wood is potentially renewable as long as its allowed to regenerate.

Hope that helps

Answer 3

There are only two renewable sources..
Geothermal (heating from the earths core etc.)
Solar (wind, water, etc.)

Solar drives all of the things listed below such as wind, water movement, etc. just different forms.

NEITHER are available indefinitely! When the Sun goes out, so does solar.. when the core of the Earth cools, so is geothermal.

However, the reason why the are "sort of " indefinite is that they replace themselves.. there is new energy flowing into the system to replace the energy we take out.. in Oil etc. we are CONSUMING the oil.. once it is gone, no new oil is made to replace it.

So, if you have a gallon of water, and drink it, you have no water.
If you have a spring that puts out a gallon an hour, and you drink a gallon, in one hour you have another gallon.

Big problem is we drink gallons, but the sun puts out ounces.. we will not be able to have such a rich energy life.

Answer 4

They are available and u don't recognize it . There are 3 renewable fuels that will comply with your preemies. They are gas ,oil,and coal Which the earth continually recycles.It starts with plants and photosynthesis. CO2 is removed from our air as following. The plants take in the CO2 and the plant holds on to the C to produce food for the plant ,and in the process it will give us back the O2 . Now that I have showed the cycle of our air recycle Now to the other cycle of what happens to the C . The CO2 accelerates the growth of the plants . Then winter comes along and the leaves die and wash down the river to the delta where the leaves deteriorate into Oil , Gas and Oil, This process is well documented ,where do u think the original fossil fuels came from??? Don't change what God started.

Answer 5

The screams alone could power Monster City for eons... So yeah, the burning of the soul themselves could be a new energy source. But it wouldn't combat Global Warming as it's not really happening...

Answer 6

the sun because it'll be there for a while and it's free.
just like the wind. there will always be wind. and it's free
