Conserving Energy!

Conserving Energy

What would happen if the world ran out of fossil fuels today?

• Heating and cooling system of most buildings would fail

• Forests would disappear as people began to burn wood for heating and cooking

• Cars, buses, and trains would be stranded

• Since televisions, computers, and telephones depend on electricity, communication would be reduced

• Although fossil fuels won't run out soon, they won't last forever

How can we preserve our energy resources?

• Increase the EFFICIENCY of energy use

• Conserve energy whenever possible

Efficiency

• The percentage (%) of energy that is lost to perform work

• The rest of the energy is "lost" to the surroundings, usually as heat

Lighting

Light emitting diode (LED) lights are providing consumers a cost-effective and energy efficient alternative to compact fluorescent (CFL) and incandescent lighting. (Source: Energy.gov)

Transportation

Engineers have improved the energy efficiency of cars by designing better engines and tires.

In many communities, public transit systems provide an alternative to driving.

Biking and walking instead of driving (when possible) helps save energy and gives you fresh air and exercise! :-)

SO what is energy conservation?

Energy conservation means reducing energy use.

- Walk to the store instead of getting a ride

- Unplug any appliances that are not in use (will still use energy when sitting)

- Turn off the lights when leaving a room

-Recycle

• yes

• no

Protecting our Natural Resources

We need to protect our natural resources so that not only us but our future generations will have them to survive.

Poll

How can we protect our natural resources?

• By not wasting them

• By using only what we need

• By using things we don't need to make something else we need.

Reduce, Reuse and Recycle

• When we stop wasting something, we reduce how much of it we use.

• We recycle something when we turn it in to a company and they use it to make new products.

• By using something you do not need anymore to make something useful is how you can reuse.
