A few reviews of this book;

The quest for safe, secure and sustainable energy poses one of the most critical challenges of our age. But how much energy do we need, and can we get it all from renewable sources? David MacKay sets out to find the answer through a forensic numerical analysis of what we use and what we can produce. His conclusions starkly reveal the difficult choices that must urgently be taken and readers interested in how we will power our society in the future will find this an illuminating read. For anyone with influence on energy policy, whether in government, business or a campaign group, this book should be compulsory reading. This is a technically precise and readable account of the challenges ahead. It will be a core reference on my shelf for many years to come.

Common sense, technology literacy, and a little calculation go a long way in helping the reader sort sense from nonsense in the challenges of developing alternatives to fossil fuels. MacKay has provided a high priority book on a high priority problem.

MacKay’s book is the most practical, solidly analytical, and enjoyable book on energy that I have seen. Through a grounded yet playfully quantitative approach, MacKay illuminates the daunting challenges associated with possible paths to sustainable energy. This heroic work gets the energy story straight, assessing the constraints imposed by physical reality that we must work within. In so doing, MacKay delivers creative and useful tools so that we may quantify, visualize, and compare our energy options on a personal scale, deciding for ourselves what adds up. Like cold water on the face, this book snaps us out of our fossil fuel delirium and makes it clear that we must get to work if we want to maintain an energy-intensive lifestyle.

Alternative Energy - What it’s all About

Posted by admin

Alternative energy is rapidly sweeping across the nation, and the world as today’s hottest environmental topic. Alternative energy topics no longer revolve around producing nuclear energy for electricity, but also include the use of products such as Ethanol in cars.

We feel that it is vitally important to educate the public on what alternative energy is, how it works, and how you can easily implement your own alternative energy solutions for your home or business.

Renewable energy is a class of alternative energy that uses natural resources such as geothermal heat, tides, sunlight, and wind, which are naturally replenished through the earth and sun and which will never be depleted. Right now, around 15 percent of the world’s energy comes from renewable energy sources. Some people tend to think that renewable energy is not very reliable because of its dependence on nature, but if one uses a combination of renewable energy sources, it can be every bit as reliable as traditional energy sources.

Types Of Alternatives Energy;

Hydro Power - Hydro power is formed by small water generators called micro-hydro turbines that are set into flowing water’s stream.
Solar Power - Solar power is made by converting sunlight into electricity using cells made from silicon, which, when exposed to sunlight, creates an electric charge.
Wind Power - Wind power is created by a turbine on a tall tower using the wind to kinetically generate electricity.
Ethanol - Ethanol is an alternative fuel to replace gasoline, made from ethyl alcohol, a common alcohol made from corn or wheat.
Biodiesel - Biodiesel is an alternative fuel for petroleum diesel and is produced from vegetable oils and animal fats.
Hydrogen - The most abundant element in the universe which can be produced from fossil fuels, biomass, or by electrolyzing water.
