Alternative energy

Between eating, playing tag and more eating Sid and I told the other bears about the alternate energies humans could use.
We broke into two groups and did a presentation.

• Wind Energy

"Humans can create energy by spinning turbines. Wind energy uses wind to spin the turbines creating energy that is cheap and clean... meaning that it does not throw green house gasses into the atmosphere. Wind energy though only works in places where there is constant wind and the wind spinners take up room. The kinetic or moving energy of wind is converted into electrical energy. The groups of wind spinners make wind farms that supply partial energy to the grid. Some towns use smaller spinners to generate their electricity without using fossil fuels.

• Solar

There are three types of Solar energy.

1. Sunlight is directed onto solar panels made up of photovoltaic cells that convert the photons energy into light energy. They are made up of semi-conductors and silicon. This type of solar energy can power small things such as human time-tellers and math-doers but this solar energy can also supply a large amount of energy to the grid. Humans can also have solar panels installed on their houses.
2. Sunlight is reflected onto a pipe carrying oil which is super heated by the light of the sun. The pipe then goes into a vat of water that steams. The steam spins turbines that produce electricity. This is known to some humans as concentrated solar power technologies.
3. The final type collects heat to heat water.. I don't see how you humans like warm and hot water at temperatures of above 60 degrees. I mean anything above 40 is horrible.

• Nuclear energy

This energy is made by using a uranium rods that are super heated . The rods are dipped in water making steam that spins turbines. This energy is dangerous because of the uranium. The nuclear reactors can have melt downs and blow up. Us bears know the risk because of the Ukraine incident in 1986.

• Hydroelectricity

Is made by water spinning turbines. It is very productive but it dams up water and can destroy the natural habitats of animals in that area. It is a pretty simple idea, but alot of energy goes into building the dam.

• Hydrogen fuel cells

Hydrogen fuel cells create electricity by making atoms bond. (most of these bears have based bechemitric which is your chemistry.) The bonding creates electricity which can spin a motor and generate power.

• Geothermal

Geothermal is electricity harnessed from the heat of the Earths inside. The inside of the earth is magma which is molten rock. Water is heated by this magma to.. yeah you guessed it make steam and spin a turbine. This energy in theory can not run out because water is renewable and the Earth's heat will never go away.

• Fusion and Plasma energy

This is not mainstream but in the future it might be used. Plasma energy is generated by plasmas which are super heated gasses. The US uses 0% plasma energy

• Bioenergy

Bioenergy is the second best alternative in the US. Bioenergy is seen in fuels such as ethanol. Some of this energy has a high cost to make and als uses alot of energy to make.

People use this knowledge and use green energy so you can protect our majestic species.
