Making the Most of Hydroelectric Energy

Making the Most of Hydroelectric Energy

Hydroelectricity is the most used renewable form of energy in the world today providing more than one-seventh of the earth’s population with power. The energy is produced from the gravitational force of the water and has been long used in history. The first half of the 20th century saw an increase in the number of hydroelectric plants not just in the United States but also across the globe. Countries that are blessed with large sources of running water such as Norway, Paraguay and China have the advantage of tapping this reserve to service their domestic and commercial energy requirement. Hydroelectricity is created using several methods the most common of which is collecting water in large reservoirs like dams and letting it pass through turbines to create electricity. The supply of power can be controlled by storing water at two levels or heights. When the energy demand is low, water is

Harnessing Energy from Renewable Sources

Harnessing Energy from Renewable Sources

The search for alternative energy sources has now escalated to global proportions. Government agencies, educational institutions and scientists are all working together to look for alternative sources of fuels other than the traditional fossil sources. The direction is to find methods that are environmentally friendly. Most people would agree that the price that’s paid for the latest technology is the progressively increasing demand for fuel. This scenario has lead to the depletion of the some of the earth’s natural resources. The objective now is to reduce the dependence on non-renewable energy like fossil fuels which are available as coal, petroleum oil and natural gas. Using alternative energy sources can bridge the gap between the high demand for fuel and tapping on a resource that will not be so damaging to our planet. This refers to new fuel sources that will not involve burning fossils or depleting the earth’s natural resources.

Teaching Energy Conservation in Schools

Teaching Energy Conservation in the Classroom

Given that classrooms all over the country are used at a minimum of 40 hours each week, the accumulated cost for consumption can be overwhelming. Older institutions often occupy large buildings with wide rooms and high ceilings rooms which results in huge energy bills for public schools across all states. By implementing energy-saving measures however, school administrators can help reduce their expenses by thousands of dollars each year. The savings can go a long ways towards helping a school district manage its budget and have enough allocation for school-related needs. Some of the practices that can be done, not just by the school administrators but also by the teachers and students to conserve energy includes: • Designate a point person for all energy management activities. The person will be in charge of evaluating and identifying different areas or units where the consumption of energy is significant. He will also be
