Young readers are introduced to the worlds extensive demand for energy and what this demand entails. Informative text, maps, and graphs will help readers understand how countries supply enough energy to meet an overwhelming demand. Brilliant photographs, fun facts, and study questions add another layer to this fascinating topic.

The ocean tides offer a clean and renewable energy source that can reduce reliance on fossil fuels. This Science Screen Report shows how Earth's tides are formed, illustrates their relationship to the Moon's gravitational forces, and explains how these principles can be applied to the construction of underwater turbines. The program also explores efforts to reduce the environmental impact of dams that are essential in the operation of undersea power...

The Earth is surrounded and permeated by gases. This program, a Science Screen Report, looks at the composition, properties, and applications of fuels and gases. Through experiments and real-world examples, it illustrates how the uses of different gases relate to their weight, combustibility, and degree to which they can be compressed or liquefied. The video also discusses how fossil fuels and gases such as methane and hydrogen are applied to heating,...

Using numerous examples to show how a very important phenomenon occurs and serves various purposes, this fascinating program takes students on a lively journey through the mechanisms and practicalities of heat transfer. Viewers are introduced to conduction, convection, and radiation and encounter the concepts of specific heat and thermal capacity. Topics include the use of heat in power stations to generate electricity; how various states of matter...

Access to affordable, sustainable energy supplies is a growing concern around the world. This program looks at successful enterprises that are providing some renewable energy solutions. In Scotland, small-scale turbines put wind power within the reach of domestic users. In Sweden, the world's first train to be run solely on biogas has been developed. In Nepal, biogas stoves are improving the quality of life in many ways. And in India, agricultural...

Nothing is so familiar, and yet so elusive, as water. A running faucet would require 136 trillion years to discharge the Earth's 326 million cubic miles of water, but only fresh water-less than three percent of the global supply-can sustain life. As we transport, utilize, and consume water, we are tempted to view it as eternally plentiful. But its protracted cycle of falling from the sky, seeping into the ground, resurfacing, and evaporating is a...

In India a new generation is enjoying the luxury of air conditioning, not just at home, but in the thousands of commercial buildings that have sprung up in the flourishing economy. With its increased energy needs India is now spewing more greenhouse gases than almost every other country-and yet there still isn't enough electricity to meet the demand. This program examines India's energy shortage and the sustainable alternatives being employed to address...

Electricity and heat-two forms of energy that American households and businesses can't do without. More and more consumers and companies are realizing that we can't rely on fossil fuels for these necessities and must switch to renewable sources. This program investigates three main ways in which solar energy is used around the world: solar hot water, photovoltaic solar panels that generate electricity for small consumers, and thermal arrays that use...
