President Obama and Stevenn Chu's Ideas on Energy

Obama and Chu have very similar thoughts when it comes to energy. When it comes to the idea of renewable energy they both agree that the world should start using this cleaner and more efficient energy sources. Obama has a plan that by 2012, 10% of our electricity will be form renewable sources. And, by 2025, he wants 25% of electricity from renewable sources. Obama actually wants to start wind farms on the ocean shores to get more energy from them. Steven Chu wants to start using solar power more than any other renewable source. He wants to start using solar paint to put on the new buildings. When it comes to nonrenewable energy sources they both agree that we should start reducing the amounts used, and also reduce the emissions of greenhouse gases into the atmosphere. Steven Chu wants to reduce the use of coal and turn it into a liquid because it is cleaner.
For drilling for fuel in Alaska, it was voted against.
And for hybrid cars, they both want to start using them more often. Steven Chu wants the cars to go 40 miles a charge at least.
These are the main ideas on the energy situation from Obama and Steven Chu.

Explaination of concept Map

A lot of things have to go into the idea to change our energy sustainability. It's not as easy as it seems. There are a lot of things to take into consideration. Such as efficiency, population growth, and cost. There is also global politics, and the types of energy (renewable and non-renewable). Then things continue to branch off those and the pattern keeps continuing on. This concept map show many of the ideas that go into energy sustainability.

(concept map set as main blog picture)

Concept Map of Energy Sustainability

1. Two trends in our concept map are cost and population growth. When the population continues to grow, we have to have more energy to support everyone on the earth. This means we have to buy/produce more energy. Buying and producing leads to us spending more money, making the cost of our energy rise.

2. Importing oil and building the materials that would be used for energy sources have a time delay effect. For getting some energy sources we have to have special ways of getting the energy. For example, gas. We have to build drills to get the gas from the ground. Building these drills takes lots of time, which makes us have to wait to get the gas. Another time delay is from importing oil. It takes a long time to get the oil from the other countries supplying it.

3. Building solar panels and wind mills have a feedback loop to cost. When we build these sources, it costs more than the Americans want to spend, which leads to a problem in us getting to actually use them, which leads to our non-renewable energy sources running out.

4. Gas companies can buy out the people who invented electric cars so that gas companies stay in business. Also, foreign gas companies can choose not to sell us fuel and cut the United States off making it so we can't use most of our electronics like cars and planes don't work.
