2. Workers roll tarps over a glacier on the
Zugspitze mountain to help prevent summer
melting. We do need to wait for future
temperature rises to see that we are in
trouble. This picture calls for a crash
program to cut down carbon emission.

industrial technologies plays an important role connect to cars in the most convenient places.
in helping U.S. industry to lead the world in These areas will be located in parking spaces
energy efficiency and productivityquot; and sidewalks in an effort to reduce carbon
emissions and to reduce our dependency for
foreign oil”
Considering the above two ideas means moving towards Lester Brown’s
Plan B and this is a good sign that at least we are trying to act now.

In his book Plan B 3.0, Brown says that wind , being the most abundant, low cost
and widely distributed makes it the center piece of Plan B

5. Solar thermal collectors simply convert light into infrared energy (heat energy).
Efficiency levels reach levels as high as 75%, which proves to be economically
when utilized in commercial and residential solar hot water systems. Brown also
says that with the cost of rooftop water and space heating systems
declining, most countries will join in mandating that all new buildings incorporate
rooftop water and space heaters.

8. Action
It means doing more.
It means choosing better.
It means making your potential a reality.
We all have the power to make a difference.
Find the way to help the environment and save money.
