RENEWABLE ENERGY RESOURCES 2013-2014

Day 3 of 3

HMMMM....

If nonrenewable resources are resources that

cannot be re-made at a scale comparable to its consumption, what are renewable

resources?

was used in 2009 in

the U.S.

How much renewable energy is used in the USA in 2012?

90.7% is nonrenewable in 9.3% is renewable

burning organic or living matter.

Why is energy from biomass renewable?

Biomass is Renewable Energy

Biomass EnergyAdvantages

1. Reliable 2. Available in most

places

3. Has been used throughout time for heat and light

 4. Easy to transport

Disadvantages

1. Does not produce much electricity

 2. Destroys habitats 3. Some air pollution

Why is energy of flowing water

renewable?

Hydroelectric EnergyAdvantages

1. Reliable, with large rivers

 2. No pollution 3. Easy to use, if you

are near a river or the electricity can be sent through power lines easily

Disadvantages

1.Destroys habitats up and down stream

2. Most rivers are already dammed (used)

Renewable

WINDEnergy from

the wind.

Why is energy from

the wind renewable?

seen one of these blades on a big truck before?

Wind EnergyAdvantages

1. Reliable, in the right locations

 2. No air pollution 3. Can produce a lot of

electricity4. Can utilize (use)

offshore areas, away from communities and most animals

Disadvantages

1. Expensive2. Doesn’t work

without wind3. Good locations

are limited4. Ugly and kills

birds/bats, loud

Renewable

GEOTHERMAL

Energy from Earth’s heat.

Why is energy from the heat of the Earth renewable?

Geothermal- How does it work? Video (2:09)

Renewable Geothermal EnergyHow geothermal energy can heat or cool buildings video (2:11)

Geothermal EnergyAdvantages

1. Reliable- Earth’s heat is always available 24/7

3. No Pollution

4. Very little negative environmental impact

5. Great for heating and cooling newer buildings

Disadvantages

1. Crust is too thick in most places to provide enough heat for a huge power plant

2. Newer, less developed technology

Renewable

SOLAR

Energy from the sun.

Why is energy from the sun renewable?

Los Vados Canyon House: Solar Vacation House

Mrs. Buckingham has stayed in this house twice. It is the coolest place, located in Moab, Utah. It relies on solar energy for all of the guests’ needs.

(Hot water, lights, dishwasher, oven, laundry, hair dryers, entertainment, etc.)

The solar panels collect energy from the sun all day and charged the batteries that were kept in a shed. There was a meter inside the house that showed how much energy was available in the batteries. At night, as she used electricity, the meters showed the battery life decreasing. That will teach you to conserve energy!

During the week, a 3 day storm passed over Utah. The sun didn’t shine… but she still needed the electricity to cook dinner, turn on the lights and have hot water. The batteries quickly ran out and the power was off.

Turn and Talk: What other alternatives could the house have to power the electrical needs?

Thank goodness there was a back up generator! By using a tank of Natural Gas, we were able to generate (make) more electricity until the sun came back out. If we had used up all of this fossil fuel, we would have had to use candles!

Solar EnergyAdvantages

1. Reliable 2. No air pollution 3. Available in

most places around the world

Disadvantages

1. VERY expensive 2. Only works with sun

light (night, storms are a problem)

3. need large, expensive batteries to store extra power
