Nuclear Power, Tectonic Collision Zones: A Risky Convergence?

The demands for the greening of electrical power are increasingly strident, no more so in Asia. But does the build up of nuclear generators pose an even bigger threat than carbon emissions? The question remains unanswered.

Bamboo Can Capture Carbon Fast, Provide Income

Bamboo, a wild grass that grows in Africa, Asia and Latin America, could help tackle climate change and provide income for local communities, a conference has heard. It can sequester carbon faster than similar fast-growing tree species such as Chinese fir and eucalyptus when properly managed, said Coosje Hoogendoorn, director-general of International Network for Bamboo and Rattan (INBAR), based in Beijing, China.

The ABC of Energy: How to Live Without Hydrocarbons?

What have hydrocarbons got to do with your life and why should you miss them when they’re gone? First, let’s define what we mean by hydrocarbons: hydrocarbons are molecules which are made of hydrogen and carbon atoms. By George H Croy. Part Six of a Gaia Discovery Energy Series based on his book "The Energy Trail – Where Is It Leading".

The ABC of Energy: The Definition of Energy  

Part Two of a Gaia Discovery Energy Series based on "The Energy Trail – Where Is It Leading" by George H Croy, available at Amazon & other good book stores. From the previous column on the ABC of Energy what we learned so far was that the Sun is not Energy, but a ‘machine’ that converts energy from one form to another. So how can we define ‘Energy’ in an understandable form? The simplest way to describe energy would be to imagine it as a ‘means to do work’. In other words, by expending energy, we are able to do things.

The ABC of Energy: What is Energy

Part One of a Series based on The Energy Trail – Where Is It Leading by George H Croy, available at Amazon and other good book stores. Most people take energy for granted. You flip a switch and the light comes on. Or twist a key and the car’s engine roars into life. Energy is so much part of our lives that we pay very little attention to it. But, answer a simple question: What is energy? You can’t see, you can’t touch it, you can’t smell it – you can’t hold it in the palm of your hand.

Towards A New Energy Future: Oil and Gas To Grow Even With Clean Renewable Energy Sources

Are we at the summit of the oil peak? Is there a finite amount of fossil fuel energy on the planet, and so, are companies like Shell rushing ahead to replace traditional oil and gas with alternative sources of energy production? What is the future of energy? These were among the questions raised at the Shell – Energy Studies Institute Energy Dialogue during the 2009 Singapore International Energy Week.

Biofuels Can Mitigate Global Warming

Currently, more than 55 percent of the energy supplies in the Philippines are derived from geothermal power, hydropower, biomass, natural gas, local coal, local oil and coco diesel. Thirty-four percent come from other countries while the remaining 10 percent are from imported coal.

Jatropha: An Alternative “Green” Source of Fuel

A study conducted by the Integrated Research and Training Center of the Technological University of the Philippines and Chemrez Technologies Inc. found that the properties of the jatropha biodiesel they produced were within the specifications in EN 14214 (European Biodiesel Standards) and ASTMD 6751 (American Biodiesel Standards). This means that oil extracted from local jatropha seeds can be converted to quality biodiesel.

Increase Energy Transfer Efficiency to Reduce Electricity Usage

In an ideal world, all of our electrical energy would be generated from fully renewable resources, the process would be pollution and loss free, and the original source, the sun, lasts forever. However, until we approach this theoretical ideal, it is important to make our domestic electricity consumption as efficient as possible, use our electrical and electronic products in a manner that minimises power use (thus energy), and be aware of where the power losses are taking place. We can make a significant difference by moving on to more energy efficient products, correctly timing when we use certain products and taking advantage of using low-energy products and lower power settings. It also helps to understand the association between energy and power, and energy transfer efficiency.

Energy Efficiency of Fossil-fuel and Electricity-powered Cars

Andrew Porter takes a closer look at how energy travels from the grid to the road, and argues that electric cars are not necessarily more energy efficient compared to fossil-fuel powered cars. Electricity generation needs to be re-examined to gain greater energy efficiencies.
