Energy Consumption Reading Questions

How does the concentration of energy in a source affect how people can use energy? (198)

The concentration of energy in a source determines how much energy people can extract from said source. For example, if a particular source has a high concentration of energy, then it will produce more energy than another source with a lower concentration.

How do the United States, China, and Kenya compare in total energy consumption? In per capita energy consumption? (198)

In 2008, the United States consumed one-hundred and five billion gigajoules of energy (22% of the global total), China consumed ninety billion gigajoules of energy (17% of the global total), and Kenya consumed twenty-two million gigajoules (0.04% of the global total). The United States consumes the most energy per capita at approximately fifty-six gigajoules per person per year. That’s roughly six times the amount consumed by the average person living in China and sixty times the amount consumed by the average person in Kenya.

How can the same energy service be provided with less energy for lighting? For transportation? (205)

The same energy service can be provided with less energy for lighting by using more-efficient light bulbs such as CFLs or LEDs in lieu of incandescents. Likewise, in terms of transportation, less energy can be used by operating more efficient vehicles with either better gas mileage or driving hybrids.

When does conservation reduce quality of life? Improve quality of life? (205)

Conservation can reduce quality of life when buildings lower their temperature in colder weather and raise their temperature in warmer weather in an attempt to conserve energy; one can argue it makes those who inhabit the building uncomfortable. Conservation can be enjoyable when participating in carpools, driving more-efficient vehicles, or living in energy-efficient homes.

Energy Overview Activity

Hello, everyone!

Today was the start of a new trimester. To kick things off, my Honors Environmental Science class broke into small groups and completed an energy chart. The goal of this chart was to test our knowledge of energy along with how it is transferred. The parameters were to sketch how we believed energy transferred from the Sun to an eagle in mid-flight. Below is my group's interpretation. We hypothesized that the thermal energy from the Sun transfers chemical energy to the grass to help it grow. We then hypothesized that that small rodents, like mice, consume the grass in another chemical energy transfer. Then, the eagle consumes mice in yet another chemical energy transfer ignored to have enough energy to fly.

Carbon Cycle Simulation - Part 2

1.) An increase in fossil fuel consumption would result in an increase in carbon in terrestrial plants. The flora population would grow or expand since flora depends on carbon to survive and there would be an excess of carbon in the Earth's atmosphere. If this were to continue for another twenty years, then the number of plants on the planet would increase significantly.

2.) An increase in total carbon concentration from smokestacks would also increase the amount of carbon in the ocean’s surface. Some marine life may be harmed by this increase since some species are not used to handling such a drastic change in their environments. Other species may thrive, such as plants, since they depend on carbon to survive.

3.) Carbon may also be found at the bottom of the ocean or high up in the Earth’s atmosphere. In fifty years, we could find excess carbon in both of those spaces, especially the bottom of the ocean.

4.) The areas most affected by the burning of fossil fuels are the Earth’s atmosphere, the planet’s supply of oil and gasoline, and terrestrial plants. An increase in carbon in the atmosphere is harmful to the planet because it accelerates the greenhouse effect, thus further warming the planet - causing extensive damage across the globe. A decrease of the oil and gasoline supply is also detrimental at the moment. Fossil fuels play a very large role in the way humans live their lives. If we run out and we do not replace our primary fuel source, serious consequences will occur. An increase in carbon in terrestrial plants is beneficial to the plants because plants require carbon to survive.
