Hydroelectric Energy Explained

What is hydroelectric energy
Hydroelectricity is basically electricity generated from the kinetic energy in moving water. It’s important to understand that the water doesn’t need to be falling, just moving! Energy created this way is called hydroelectric power or hydropower.
At present hydropower is the most popular form of renewable energy and accounts for over 80% of the electricity generated from renewables and over 20% of the worlds electricity supply.

Fuel Cells - An Environmental Saviour or Just a Load of Hype

A fuel cell is basically an engine that produces electricity. Which is not that different in it’s make up to its cousin, the standard battery. As the cells found within are very similar and as with batteries it produces electricity by means of a chemical reaction. But unlike standard batteries that store electrical energy chemically and need to be recharged, the energy in fuel cells is derived from an external fuel source.

What exactly is Nuclear power and how does it work

Nuclear power has once again found itself in the headlines, but this time it’s not for a disaster such as Chernobyl or three mile island, but as a potential saviour of the environment (nuclear plants produce almost no emissions and so don’t contribute to the greenhouse gases in the atmosphere, unlike traditional fossil fuel plants) and relatively clean supplier of our global energy needs. There has been a great deal of media attention on alternatives and how they are going to help clean up the world as well as give us all of the energy we will need.

A Beginners Guide to Renewable Energy

Energy impacts every facet of our lives and as we have seen recently in the news and the recent spike in Oil Prices, the standard fossil fuels we have been using for the bulk of our energy production are gradually being depleted. This is not the only concern though as the polluting and environmental damage caused by Coal, Oil and Gas Exploration alongside refining and transportation is taking a heavy toll on the health of our planet and cleaner alternatives are coming back in vogue.

Solar Energy - What is it and what does it promise?

Using the sun to benefit society is nothing new and is something we have been doing for thousands of years, whether it’s starting fires, drying meat, or powering your house we are continually finding increasingly complex ways to utilise this limitless resource.
How Does Solar Energy Work

Solar Energy - Are Our Expectations Too High?

Since the mid 1960’s we have been hearing all the glorified reasons why solar energy is going to be the undisputed champion of cheap, renewable energy production that will save us all from the potential negative environmental effects of other energy sources such as oil, coal and nuclear energy.

The Truth About Biofuels!

Just a few decades ago, “biofuels” were all the rage in the media, as many well respected “power pundits’ predicted that they would eventually prove to be a leading “vanguard” movement amongst a variety of well touted alternate energy options.
Then recently, over the past 2 years, as the prices of crude oil began to rise to historically elevated levels and even the most dedicated “oil optimists” began to worry when or if the ascent would top off , ‘biofuels” where once again purported to be our “Super Saviors” that would eventually satisfy a great deal of our energy needs.

A Guide to Geothermal Energy

What is Geothermal energy
Geothermal energy is produced by utilising the heat from water reservoirs deep underground which have been heated by hot magma that lies close to the earth’s surface.
The majority of Geothermal resources are normally found along tectonic plate boundaries where a large amount of volcanoes and earthquakes are concentrated.
There are various methods in use by geologists in locating these reservoirs, but the only way to be certain is to drill a well and test the temperature.

Harnessing the Power of the Sun: The Solar Power Plant

It’s been staring us in the face for the past four-plus billion years. One of the cleanest, greenest and most renewable energy sources we could ever know: the sun. However, its massive power potential has yet to be fully harnessed due to the lack of a way to store it. As soon as the sun goes down, solar power ceases. It’s as simple as that. Scientists the world over have been searching for a way around this problem, and as of recently, may just be in reach of a solution.

How Does Tidal Energy Work

How Does Tidal Energy Work
Tidal energy is energy obtained from changing sea levels (the tide moving from high to low and vice versa.) This renewable energy source has great potential as tides are much more predictable than wind power and solar energy which are not at all consistent (seasons, bad weather, etc...)
There are three main ways to harness tidal power, these are:
