The Importance Of Rainforests - 2006-12-10
By Sebanti Ghosh

Rainforests, by virtue of their abundant renewable natural resources, have for timeless periods provided the humankind with amenities for survival and well being, including food, clothing, fuel, condiments, products of industrial use, and even remedies for ailments. The loss of rainforests has an intense and overwhelming consequence.

The rainforests house the Earth's richest biological resources. Almost half of the world's biodiversity will be extinct or severely endangered in the next few years if this rainforest deforestation continues. Approximately ten million aboriginal people lived in the rainforests of the Amazon basin five centuries ago. Today the numbered has dwindled to less than 200,000. Along with the loss of the native tribes, their vast knowledge of medicinal uses of the diverse herbs of the rainforests is also gone irrevocably.

Alkaloids are abundant in the rainforest plants. Many such alkaloids have long-established medicinal use. 121 prescription drugs sold all over the world at present are derived from plant-parts. The plants in the rainforests are the sources of about 25% of pharmaceuticals used in the Western countries. But most of these plants are yet to be analyzed by biologists for their active ingredients and potential uses.

It has been found that more species of birds reside in a single biosphere reserve in Peru than the whole United States. Forty three ant species was found on one single tree in Peru. This number approximately equals the number of species of ants in the British Isles. The number of species of fish in the Amazon River surpasses the number found in the total Atlantic Ocean. These figures bear proof to the astounding biodiversity of the Amazonian rainforests. Accordingly, the loss of even one acre of tropical rainforest transpires to the loss of a staggering amount of plant, animal and microorganism species, along with the loss of their possible uses.

It is possible that cutting down the rainforest may result in losing the potential cure for cancer or AIDS that might have been discovered in an untested or unknown plant from the forest. So in every sense, the wealth offered by the intact rainforest exceeds by far the value of the supplies obtained when the trees are felled for industrial purposes.

Save the rain forest!

Eco Travel World Wide - 2006-12-10
By Cass Hope

Although the words Eco travel have been popping up a lot more over the past few years, its definition is often misunderstood or not known at all. Possibly you have also heard the word Eco tourism and they are used interchangeably because of their common definition. So what do they mean? Eco travel is planning a responsible vacation to places that conserve the environment. They also contribute to the well being of their community while practicing ethical policies.

The amount of interest in Eco friendly travel has soared, as people become more and more aware of environmental issues. Recycling and reducing vehicle emissions. Lowering the use of energy all makes a difference. Now your Eco travel vacation can also make a difference.

There are different things to look for to know if the vacation your are planning is environmentally and socially friendly. Let’s say for an example you went to a resort. You would check if they use environmentally friendly, recycled products? Are they committed to preserving their wild and marine life and the environment? Increase knowledge of local community and benefits socio economically and affordability? Not using wasteful products to make the area more attractive? Do the profits go back into the community? Do they employ local people and pay them fair wages, which is referred to as fair trade? These are all things to consider before deciding on your destination

Government and local communities are starting to work together to conserve their environment while providing much need employment in the area. There are many programs now available to help people in the tourism industry and program directors increase their knowledge of Eco travel, Eco tourism. Consumers that are ethically aware of fair trade have drastically increased sales in the tourism industry by over 50% on any given holiday.

There are now a wide variety of areas in different Countries that offer Eco travel vacations. The industry has grown so much over the past few years that it has become difficult to choose which one. From Costa Rico to Hawaii to Antarctica the choices are endless. Be aware of conservation of our environment and make Eco travel part of your next vacation.

10 Ways to Save Money on Your Home Heating - 2006-12-10
By Roger Wakefield

If you have an old fashioned gas or electric fire, you could be burning money AND damaging the environment. It may well pay huge dividends to replace your old heater with a new high efficiency model.

Modern gas fires are among the world’s most efficient home heating appliances. They not only look beautiful, but they provide more warmth and comfort from less fuel consumption than ordinary domestic fires.

Many modern gas fires are room-sealed with glass fronts. High efficiency balanced flue gas fires can be installed with or without a chimney. They draw air from outside the room for combustion and expel waste gases to the outside using a flue that is fitted through an outside wall. This technology combined with superior design means that they can operate at up to 85% efficiency, only wasting 15% of the gas which they consume.

Conventional flue gas fires are also room sealed, but are fitted directly into an existing chimney, heating the air from outside using natural convection. These fires can operate at over 90% efficiency and can all be run on both natural gas and LPG.

If you don’t have gas, why not consider one of the modern high-efficiency electric fires. The best modern electric fires are designed in a unique way to maximise style and comfort, whilst minimising the consumption of electricity. They use LED technology to produce a realistic flame picture that is the closest thing to a gas fire or a solid fuel fire you will ever have seen. They have a heat output of 2000 watts, enough for an average sized living room, and yet they consume considerably less energy than ordinary electric fires.

Whether or not you are thinking of installing a new fire in your home, here are some other ways that you can save money on your home heating:

1. Turn down the thermostat on your central heating by just one degree. This could save you 10% on your heating bill. Over the year, it will also release about 240 kg less carbon dioxide into the atmosphere, equivalent to the amount absorbed by about 80 trees!
2. Check your gas and electricity suppliers to see if they’re the cheapest. An average house could save more than £100 per year by switching suppliers.
3. Don’t heat rooms that you don’t use – or heat them at a lower temperature.
4. Only boil a kettle containing as much water as you need.
5. Make sure all draughts are sealed in doors and windows.
6. Fit loft and cavity wall insulation. Some councils give grants for this work.
7. Don’t leave TVs, DVDs, stereos etc on standby. It wastes electricity!
8. Fit energy saving light bulbs and turn off lights when you leave the room.
9. Shower instead of taking a bath, and don’t stand under the shower for longer than you need to.
10. Hang out the washing rather than using the tumble drier.

Non-Green Electrcity Generation - 2007-01-30

Fossil Fuels

At present, most of the UK’s electricity is generated through the burning of fossil fuels. This includes coal (33%) and natural gas (39%).

How is electricity produced from fossil fuels?
The fossil fuels are burnt to produce steam. The steam then powers a turbine, which spins a generator to produce electricity.

Why are fossil fuels bad?
Fossil fuels are non renewable and therefore cannot be replaced. Once they have been consumed, they are gone forever. But, more importantly, the burning of fossil fuels emits CO2, which contributes to global warming.

Nuclear Power

Approximately 20% of the UK’s electricity is currently produced from nuclear power. Like fossil fuels, a nuclear power plant produces steam that powers a turbine and spins a generator to produce electricity.

Nuclear power is seen as a clean green alternative to fossil fuels because it does not emit CO2, so does not contribute to global warming. Whilst this is true, there is massive risk with nuclear power. If anything goes wrong with the power plant, it can create nuclear fallout with devastating impact. A nuclear power plant is susceptible to a terrist attack for this reason. The waste that a nuclear power plant produces is very dangerous and at this stage, there is no effective way of disposing of this waste.

Renewable Energy

Renewable energy is an alternative to the burning of fossil fuels or nuclear power. Renewable energy is much better for the environment as it does not produce CO2, so does not contribute to global warming and it is not a finite resource, so it can be reused. The main renewable energy sources are: wind, solar, hydro, biomass, geothermal, tidal, wave and ground source. At present, only 4% of the UK’s energy means are met by renewables. However, there is untapped potential to be explored and substantially increasing the use of renewable energy can help reduce global warming and reduce our reliance on nuclear power and fossil fuels.

Green Alternatives

Wind
Wind turbines harness the immense power of the wind to generate electricity. Wind turbines are ideally suited to the UK’s vast coast line, where the wind is often consistent and strong. Wind turbines can be used with good effect in almost any rural or urban location. You can even use your own wind turbine to produce enough electricity for your house. If you produce more than you need, you can sell the surplus to the national grid for others to consume. You are in effect becoming a mini power station.

Solar
Solar power works by converting sunlight into electricity directly using a solar photovoltaic (PV) panel. It does not even need to be a sunny day to work effectively.
Solar can be used in any environment including urban cities. Solar panels can easily be mounted on rooftops. It is even possible to construct solar roof tiles that blend into the normal tiles.

Hydro
Hydropower works by using the power of water to spin a turbine to produce electricity. Hydropower currently produces approximately 1% of the UK’s electricity.

Biomass
Electric power stations can use specially grown plants or agriculture waste to generate electricity. Plants absorb carbon dioxide as they grown and then release it when they are burnt. The amount they release is cancelled out by the amount that they absorb, so biomass is actually a carbon neutral form of generating electricity.

Geothermal
Hot rocks are buried under ground. Geothermal electricity can be produced in some parts of the world by using the steam that is naturally produced by the hot rocks to spin a turbine. If steam is not produced naturally, it is possible to pump water down onto the rocks, which is then heated to create the steam.

Tidal
Tidal power is a dependable source of electricity that has been used in the UK for many years. Barrages are created to trap water at high tide. The water is then released at low tide through turbines to generate electricity. Marine current turbines can also be constructed to harness the power of tidal currents.

Wave
The sea and ocean around Britain produced some of the most powerful waves in the world. It is possible to tap into this to produce electricity using a variety of methods.

Introduction to Electric Bicycles - 2007-01-30
Electric bicycles are road-legal for ages of 14+ years, require no road tax, no licence and no insurance. They also give off no emissions and if the batteries are charged with electricity from a green energy supplier (or your own windmill) they will run entirely from renewable sources!

Electric bicycles have a legal maximum speed limit of 25kph (15mph), have to weigh less than 40kg and are of a “pedelec” type. Pedelec means that the rider has to pedal to activate the motor. The motor is therefore an assist to cycling rather than a replacement. (The rule of having to pedal is a European law. Current UK law however suggests that you can use an electric bicycle without having to pedal. While the law is a bit unclear at the time of writing no legal actions have yet been imposed against non-pedelec bicycles in the UK).



So, when is an electric bicycle useful?

One thing we sometimes hear at ecocentra is the belief that electric bicycles are for lazy cyclists and therefore actually bad for our health and the environment. Dispel this notion though; –Electric bicycles are for fit motorists! Take for example long commutes, hilly routes or windy days. These are all applications where the majority of people would not consider a normal bicycle and it is here that the electric motor really comes into its own. Electric assist can get you there faster and at a healthy amount of exercise.


How do I choose an electric bicycle?
When choosing an electric bicycle the main factors will be the range, weight and quality of build.

The lighter the bicycle the more fun and versatile the bike. Remember that there will be occasions when you want to ride without the battery assist and if the bike is very heavy this will not be much fun. Ideally look for a bike that weighs less than 25kg.

Range is important too and, while it sounds obvious, you should make sure it would be enough for what you are planning to use it for. Manufacturers provide a quote of the range but these are often derived from ideal test conditions and we recommend using these quoted figures with a pinch of salt. As a guide you should only expect them to have a range of ¾ of the quoted figure.

We have compiled information on some good electric bicycles here but a great place for electric bicycle reviews is at www.atob.org.uk. They have a lot of excellent information on the site and if you want a review of a particular bike you can order back issues.

Salary Sacrifice
There is currently UK Government tax break that allows you to buy a bicycle for around 60% of the retail price. Essentially this scheme allows you to write off the part of the value of a bicycle (or electric bicycle) against your earnings and hence not pay income tax or national insurance on that part of your salary. It also saves you the VAT on the bike and the total discount is around 40%. You will have to get your employer to fill out a simple form and the bicycle will get paid off from your salary over a 12-18 month period. Some bike sellers such as Evans Cycles and Powabyke have online information and forms but you are not limited to these retailers.
