The rise of renewable energy
- Greenhouse gas emissions can succeed through increases in energy efficiency alone.
- To counter the alarming trend of global warming, the U.S. and other countries must make a major commitment to developing renewable energy sources that generate little or no carbon.
- Electricity produced by crystalline cells has a total cost of 20 to 25 cents per kilowatt-hour, compared with four to six cents for coal-fired electricity, five to seven cents for power produced by burning natural gas, and six to nine cents for biomass power plants.
- Solar cells can now be made from a range of materials, from the traditional multi-crystalline silicon wafers that still dominate the market to thin-film silicon cells and devices composed of plastic or organic semiconductors
- If the U.S. constructed enough wind farms to fully tap these resources, the turbines could generate as much as 11 trillion kilowatt-hours of electricity, or nearly three times the total amount produced from all energy sources in the nation last year.
- The wind industry has developed increasingly large and efficient turbines, each capable of yielding 4 to 6 MW. And in many locations, wind power is the cheapest form of new electricity, with costs ranging from four to seven cents per kilowatt-hour.
- The federal government has used such programs with great success to curb other pollutants, and several northeastern states are already experimenting with greenhouse gas emissions trading.

There are many renewable energy with no emissions. If we continue creating more of windmill or solar energy, then we shall reduce a lot of C02 and save electricity. Also, keeping our air clean to decrease lung cancer patients. Share, spread out, and educate people about how precious the renewable energy is.
So what?
- Create more renewable energy with no emissions to reduce CO2 in the atmosphere and reduce pollutants.
What if?
- we all using renewable energy?

What does this remind me of?
- This reminds me of the "Pro vs. Cons" activity in class
