Heat Trapping Gases & Other Climate Change Influences

Part 4 of United States Climate Change Impact. Carbon dioxide concentration has increased due to the use of fossil fuels in electricity generation, transportation, and industrial and household uses. It is also produced as a by-product during the manufacturing of cement. Deforestation provides a source of carbon dioxide and reduces its uptake by trees and […]

United States Climate Change Impact Summary

Part 2 of United States Climate Change Impact. Observations show that warming of the climate is unequivocal. The global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases. These emissions come mainly from the burning of fossil fuels (coal, oil, and gas), with important contributions from the clearing […]

Geothermal Energy: Power from the Depths of the Earth

Part 1 of Geothermal Energy: Power from the Depths of the Earth. The Earth’s crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the […]

Why should you buy a photovoltaic system?

Part 4 of Get Your Power from the Sun. People decide to buy photovoltaic systems for a variety of reasons. Some people want to help preserve the Earth’s finite fossil-fuel resources and reduce air pollution. Others want to invest in an energy-producing improvement to their property. Some people like the security of reducing the amount […]
