# Is food a renewable energy source?

It is a Non- Renewable source of energy because when food is waisted and it runs out it cannot be renewed.

# How is the steam used to produce electricity?

A 300 grams of water takes about 90 seconds to boil in a 2 kW kettle, so that is 2000 watts x 90 seconds which is 180,000 Joules of energy.

But to convert that water completely into steam requires an extra 300x550x4.2 Joules, which is nearly 700,000 Joules.

So converting it to steam takes 4-5 times as much energy as boiling it. That is why it takes a while for a kettle to boil dry.

# How can geothermal be used to produce electricity?

Using a geothermal transformer

# What are the last 2 steps in an electrical power plant?

The last two steps are:

1. The steam or gas spins the turbines
2. the turbines then turns the electric generators producing elecricity

# What is the science behind a rosin bag?

A rosin bag is designed to keep your hands tacky so you have plenty of grip on the ball in Baseball.

# What is the purpose of Geothermal?

Geothermal is a reference to a naturally occurring phenomenon. It refers to the heat of the Earths core and has no intrinsic purpose. It's used by humans to produce electricity, to heat buildings and greenhouses, etc.

# How does geothermal energy is used to generate electricity from steam?

The heat from the earth is used to heat water. The water is used to turn a turbine - which generates electricity.

# What do we use geothermal for?

1. Heating and cooling houses.
2. Generating electricity.

underground heat

# Some argue the geothermal energy should be the main energy source for the US what argument could be useful to dispute this idea?

Geothermal power can only be used in some areas (apex)

# Is geo thermal energy non renewable?

Yes, fundamentally geothermal energy is NOT a renewable resource. The souge heat for geothermal energy is the heat from Earth's core (caused by the fission of heavy, radioactive isotopes). This heat is dissipating and will not be renewed. Also where geothermal energy is extracted, the turnover rate in the crustal rocks is so slow that the heat source is quickly cooled to the point of exhaustion. (Note, highly volcanic areas are an exception to this).

# Is geothermal energy a fossil fuel?

No. Fossil fuels are coal, oil and natural gas. Geothermal energy is a clean renewable energy powered by the heat from the centre of the earth. It is the only renewable energy whose power does not come from the sun.
