Discusses a number of issues related to fossil fuels versus renewable energy.

Most people use a gas-powered vehicle of some kind on a daily basis. But what would happen if we were to run out of gas? This book evaluates a situation quickly coming to the forefront of our cultural consciousness. Through expert analysis, informational text, and seminal public documents, the problem is assessed and evaluated in a manner that makes readers understand the urgency of the situation.

Provides a history of alternative energy, and offers advice on pursuing a career in the field. Discusses common careers, and includes an interview with an expert in solar energy. Includes career statistics, color photographs, a glossary, and further resources.

"From the sun's powerful rays to the national power grid ... [this book follows] the journey of sunlight from source to resource ... [Also explores] other ways of generating electricity too, and consider[s] each one's advantages and disadvantages"--Back cover.

Discusses oil as an energy source and possible alternative renewable energy sources.

"For centuries, falling water has been used in parts of the world to create energy to run grinding stones at mills and irrigation systems for crops. This interesting book shows how the use of this 'clean' form of energy, called hydroelectricity, is being expanded to help us build a more sustainable future. Discover how other forms of water-based energy, such as energy from ocean waves and tides, are being harnessed and used to help create electricity to power our homes, offices, and factories."--Provided by publisher.

Contains a collection of articles with varying perspectives on issues related to energy alternatives.

Most of our energy comes from fossil fuels, but eventually we will run out. We will not, however, run out of sunshine or wind or waves. The center of the Earth will always be extremely hot, and fuels like switchgrass and algae can easily be regrown. These types of renewable energysolar, wind, water, geothermal, and biomasshave the potential to power a cleaner future. The countries of North America have always had plentiful natural resources. But the exploitation of these resources comes at a cost, and in certain cases, some have wondered if that cost is too high. North American Natural Resources explores all facets of this vital aspect of our economy. Readers will investigate the natural history, human use, technology, environmental impact, and economic significance of the most significant resources on the continent.

Describes the form of energy called biomass, explains how it is created and used, and why it could be a more sustainable power source.
