Top ten cheap eco-friendly cars

With the urge for fuel efficient or environmentally friendly cars, there has been a greater consideration given by car companies to build their next electric car which has a very low CO2 emission rate. With all the car companies below is a list of cheaper of those cars.

1: Seat Ibiza, 1.4 TDI 80PS Ecomotive, diesel
CO2 (g/km): 99
Price: £11,000
Seat's probably not the first name you think of when it comes to green cars, but this three-door supermini's both cheap to buy and cheap to run.


2: Volkswagen Polo Bluemotion, 1.4 TDI 80PS
CO2: 99
Price: £11,995
This little diesel has all the solid German build quality you'd expect, plus an incredibly economic engine that'll make the man at the garage a distant stranger.

3: Honda Civic Hybrid 1.4 IMA ES
CO2: 109
Price: £16,300
As the cheapest hybrid in the UK, the Honda Civic Hybrid is a good, small family alternative to the Prius -- so long as you can stomach automatic transmission.

4: Renault Megane Sport Hatch 1.5 dCi 86 Expression 3 door
CO2: 117
Price: £13,000
Like Citroen, Renault's one of the unsung French brands which has been doing a huge amount to cut emissions across its range. This small family car is a particularly economic example.

5: Citroen C3 1.6HDi
CO2: 118
Price: £13,000
The Citroen C3 is an efficient, straightforward car with a big boot and not quite enough legroom at the back.


6: Ford Focus ECOnetic 1.6 TDCi
CO2: 115
Price: £15,800
This is a brand new version of Britain's most popular car. It's incredibly fuel-efficient and, if it's similar to the Ford bioethanol Focus we reviewed, will make for a good reliable drive.

7: Renault New Laguna Hatch dCi 110
CO2: 130
Price: £17,100
As it emits 130g of CO2 per kilometre the Laguna is just on the borderline of being a greener option, and it's also on the pricey side. But it has some of the best green creds you'll get for a car of this size.

8: Skoda Fabia Estate1.4 TDI PD 80PS
CO2: 109
Price: £13,100
No more funny jokes about Skodas. This one is big and clever -- not to mention as cheap and green as estate cars come.

9: Peugot 207 SW, 1.6 HDi
CO2: 119-123
Price: £13,900
Another big but green option. According to Autoexpress it's a little dear, but it has everything you could want in an estate.

10: SMART Fortwo Cabrio
CO2: 113
Price: £10,500
With their heavier frames for safety and structure, it's surprising any open-top cars made this list. But we can fully recommend this Smart, since it emits so little CO2 and only costs mite over £10K.

How to make compost

1
Choose a site that is handy to your garden and kitchen, yet out of plain sight.
Step
2
You don't need a bin to make compost—a pile of leaves, grass clippings and other yard wastes will do—but a bin keeps the compost contained and looks neater. You can corral compost in a simple wire column made from a 4-foot wide by 8-foot long piece of stiff wire mesh.
Step
3
You can also buy a more permanent bin or build a three-bin compost system made from slatted wood or recycled pallets. Leave the bins open on one side so you can add compost materials and turn the pile easily. Cover the top of the bins with a sheet of plywood if you live in a very rainy climate. A three-bin system allows you to turn the compost from one bin to another and store finished compost until you are ready to use it.
Step
4
The two basic elements that make up compost are green garden debris (grass clippings or old annuals) and brown garden derbis (dry leaves). Green ingredients are high in nitrogen and brown materials are high in carbon. Adding too many greens can make the pile smell bad. Do not add animal waste, meats, oils, dairy, diseased plants, weeds that have gone to seed, or plants treated with pesticides or herbicides to your compost.
Step
5
Compost piles with a balance of one part green to two part brown materials break down fastest. The easiest way to achieve this balance is to add one garden forkful of green material to the pile, top it with two forkfuls of brown material, and mix them together. Continue adding greens and browns until the pile is at least 3 cubic feet (3 ft. x 3 ft. x 3 ft.). Piles of this size heat up quickly and break down faster.
Step
6
Add in a shovelful of finished compost or garden soil to help kick start the microbial activity in your pile.
Step
7
Compost also needs the correct amount of moisture to breakdown. Compost with the right moisture level should feel like a damp, wrung-out sponge. Too much moisture can cause temperatures to fall within the pile (and make it smell). Too little moisture slows down the decomposition rate and keeps the pile from heating up. Check your compost pile's moisture level once a week and adjust it if necessary by adding water to increase moisture or more browns to help dry the pile out.
Step
8
Turn the pile once a week to move material from the outside of the pile in. Turning also keeps the pile from compacting, which reduces airflow and slows down decomposition.
Step
9
You should have finished compost in about two months. You'll know your compost is finished when it no longer heats up and you can't identify any of the original materials. The compost should be dark brown, moist and earthy smelling. Dig finished compost into your garden's soil. You can use partially composted material as mulch.
Step
10
You can also build a very basic, passive compost system by simply piling up leaves, grass clippings and other yard waste into a pile in a secluded corner of your yard. The compost will be ready when the original ingredients are unrecognizable, usually in about 6 to 12 months. Compost at the bottom and middle of the pile typically "finishes" first.

A bright way to cut your power bill

Compact fluorescent light bulbs cost more off the shelf, but they'll save you money and time in the long run, and help the planet. Here's how the math pencils out.

I regularly mention using compact fluorescent lights for the home, but I haven't laid out the entire case for CFLs in one place before. It's time to change that.

Below are five huge reasons why you should switch your home light bulbs to CFLs today. (Even if you already use CFLs, you may want to read this list. There's something on it for you, too.)

For this exercise, I'm going to refer to a six-pack of General Electric 26-watt CFLs, which you can get from Walmart.com for $15.16, giving them a cost of $2.53 a bulb. These bulbs claim 100-watt equivalence, but I actually find their brightness to be between that of a 75-watt and a 100-watt incandescent bulb, so we'll compare them to 75-watt bulbs. For comparison's sake, a four-pack of GE's 75-watt incandescents at Amazon.com is $4.10, or $1.03 a bulb.

1. The bulbs themselves are cheaper.
2. The per-hour cost of energy for CFLs is cheaper.
3. The time involved is less.
4. They cut carbon emissions.
5. You can save $1 on a GE CFL during July 2007.

Green cars in line for better lithium-ion batteries

SAN JOSE, Calif. - The lithium-ion battery, already a fixture in personal electronic devices, soon will become the answer to high oil prices and environmental concerns as it bulks up to power rechargeable electric vehicles, government, university and industry panelists predicted Monday.

But although the technology shows great promise, battery makers worldwide still are grappling with high costs, the impact of charging and depletion on battery life, keeping the batteries cool and other issues, according to panelists at the Plug-In 2008 conference in San Jose.

Tien Duong, who works in emerging battery technology with the U.S. Department of Energy, told the group he believes lithium-ion batteries are ready to start displacing the nickel-metal-hydride batteries now used in many hybrid gas-electric vehicles.

51 Things We Can Do to Save the Environment

Can one person slow global warming? Actually, yes. You—along with scientists, businesses and governments—can create paths to cut carbon emissions. Here is our guide to some of the planet's best ideas.

1.Turn Food Into Fuel
By Alice Park

Are corn husks better than corn for producing energy? Ethanol is the alternative fuel that could finally wean the U.S. from its expensive oil habit and in turn prevent the millions of tons of carbon emissions that go with it. The Department of Energy has doubled its 2005 commitment to funding research into biofuels—any non-petroleum fuel source, including corn, soybean, switchgrass, municipal waste and (ick) used cooking oil. Already, half of the nearly 11 billion bushels of corn produced each year is turned into ethanol, and most new cars are capable of running on E10 (10% ethanol and 90% gas).

Yet the eco-friendly fuel is beginning to look less chummy of late. Some of the 114 ethanol plants in the U.S. use natural gas and, yes, even coal to run the processors. And ethanol has to be trucked. Existing gas pipelines can't carry it because it corrodes iron. Then there are the economics. Producers depend on federal subsidies, and increasing demand for corn as fuel means the kernels keep getting pricier.

That's why researchers are prospecting for more alternatives, preferably ones that don't rely on food crops or a 51 cents-per-gallon tax break. Municipal waste, wood pulp and leftover grain and corn husks are all quite attractive; they can produce something called cellulosic ethanol, which contains more energy than corn. But they don't give up their bounty easily, so for now they're more expensive than corn-based ethanol to produce. Undeterred, researchers at several cellulosic-ethanol plants are developing innovative enzyme concoctions and heating methods to make the process more economic. Nothing like haste to make something out of waste.

2. Get Blueprints For a Green House
By Laura Locke

Reducing your impact on the earth is not just a question of what you drive but also of what you live in. Residential energy use accounts for 16% of greenhouse-gas emissions. If you begin thinking green at the blueprint stage, however, low-tech, pragmatic techniques will maximize your new home's efficiency. Installing those systems from the ground up is cheaper than retrofitting. "Doing simple things could drastically reduce your energy costs, by 40%," says Oru Bose, a sustainable-design architect in Santa Fe, N.M. For example, control heat, air and moisture leakage by sealing windows and doors. Insulate the garage, attic and basement with natural, nontoxic materials like reclaimed blue jeans. Protect windows from sunrays with large overhangs and double-pane glass. Emphasize natural cross ventilation. "You don't need to have 24th century solutions to solve 18th century problems," Bose says. Next, consider renewable energy sources like solar electric systems, compact wind turbines and geothermal heat pumps to help power your home. When you're ready to get creative, GreenHomeGuide.com will help you find bamboo flooring, cork tiles, and countertops made from recycled wastepaper.

How you can create less trash..

# Buy items in bulk from loose bins when possible to reduce the packaging wasted.
# Avoid products with several layers of packaging when only one is sufficient. About 33 of what we throw away is packaging.
# Buy products that you can reuse.
# Maintain and repair durable products instead of buying new ones.
# Check reports for products that are easily repaired and have low breakdown rates.
# Reuse items like bags and containers when possible.
# Use cloth napkins instead of paper ones.
# Use reusable plates and utensils instead of disposable ones.
# Use reusable containers to store food instead of aluminum foil and cling wrap.
# Shop with a canvas bag instead of using paper and plastic bags.
# Buy rechargeable batteries for devices used frequently.
# Reuse packaging cartons and shipping materials. Old newspapers make great packaging material.
# Compost your vegetable scraps.
# Buy used furniture - there is a surplus of it, and it is much cheaper than new furniture.

# Wash and dry only full loads of laundry and dishes.
# Follow your community's water use restrictions or guidelines.
# Install a low-flow shower head.
# Replace old toilets with new ones that use a lot less water.
# Turn off washing machine's water supply to prevent leaks.

consumption of water efficient is an important issue in saving the environment.

Kandalama Hotel: how they went environmental

Have you ever seen a hotel like this before? a hotel which is actually built around the nature Literally? Hotel Kandalama a Aitken Spence Group Hotel is located in the city of Dambulla in Sri Lanka. This hotel is classified as 5 Star Hotel and is one of my favorite hotels in the world.

"Heritance Hotels represent a unique Green Philosophy that combines responsible tourism with environment friendliness. The Heritance Kandalama has won awards as the most eco-friendly hotel in the world. It is by far the most environment friendly hotel in Sri Lanka..."

Innovations: Inflatable Solar Panels

Water heaters are one of the primary power-hungry devices in most households. That’s why the prospect of an affordable solar panel system is particularly exciting. I have always argued that green energy alternatives must be affordable in order to be a viable choice by the masses.

The inflatable SolarStore by British company, IDC, is planned for commercial availability at less than 100 pounds ($200). While most domestic solar systems take 10-20 years to return the initial investment, IDC promises that their system will pay back its cost in six months.

The company press release notes, “Although the SolarStore is inflatable, the structure of the system is strong and robust and it is anchored down by the weight of 30 litres of water. It is manufactured from a heavy-duty polymer that is designed to protect against dirt and rain. SolarStore is an eco-friendly solution, which saves nearly 0.2 tonnes of CO2 emissions each year.”

I think this is great news, and I hope we see more and more such viable environmental alternatives in fashion, technology decor and design.

Innovations: eFuel

With the never ending increase in gas prices, people have started to think about fuel alternatives. E-Fuel Corporation, a company in California, has introduced the EFuel 100 MicroFueler, a device that weighs about 200 pounds, that uses 110 or 220 volt power supply and a wastewater drain that is just like a washing machine. Using just water, raw sugar and yeast, consumers can create 100 percent ethanol at the push of a button.

Ethanol is a great alternative to gasoline; however, the MicroFueler costs close to $10,000 and requires a lot of electricity, water and sugar to create a sufficient amount of ethanol.

Thankfully, E-Fuel Corp hopes the changes in the North American Free Trade Agreement will allow the importation of inedible or “ethanol-grade” sugar from Mexico for as little as 2.5 cents a pound, thereby reducing the cost of making ethanol.

E-Fuel plans to distribute this device at the end of this year.

Where will Crude Oil Price end?

an exponential growth in Price of a barrel of Light Crude oil..
OPEC has seldom been effective at controlling prices. While often referred to as a cartel, OPEC does not satisfy the definition. One of the primary requirements is a mechanism to enforce member quotas. The old joke went something like this. What is the difference between OPEC and the Texas Railroad Commission? OPEC doesn't have any Texas Rangers! The only enforcement mechanism that has ever existed in OPEC was Saudi spare capacity.

As crude resources depleting in the world, and Mid eastern countries continue with Chaotic nature what will happen to supply of Crude Oil(CO)... This calls for greater need of alternative energy resources... As the CO demand increases today will the equilibrium price of CO continue to go up? I leave you today with these questions...

Wind Mill: power of wind

How a wind turbine works

Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, a turbine uses wind to make electricity.

The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity The electricity is sent through transmission and distribution lines to a substation, then on to homes, business and schools.

The advantages of wind power

The advantages of wind power are obvious: the energy is free and completely renewable, there are no hazardous emissions, and there are no adverse environmental impacts.

In 1990 in California alone, wind power offset the emission of more than 2.5 billion pounds of carbon dioxide and 15 million pounds of other pollutants - the same amount of air quality provided by more than 150 million trees.

Air conditioning your home

01. Maintain your central air conditioner by cleaning the outside compressor with a garden hose (be sure to shut off power at the fuse or breaker first). Keep plantings at least one foot away for adequate airflow.

02. During late afternoon and early evening, turn off unnecessary lights and wait to use heat-producing appliances. It's also a good idea to shade south- and west- facing windows during the hottest part of the day.

03. Plant a tree. One well-placed shade tree can reduce your cooling costs by 25 percent. For maximum benefit, place leafy shade trees to the south and west, and evergreens to the north.

04. Use ceiling fans to help circulate air throughout the house, and make sure your attic is properly ventilated. A ceiling fan should run clockwise during the summer, and counter-clockwise during the winter.

05. Set the fan on your central air conditioner to "on" rather than "auto." This will circulate air continuously, keeping the temperature more even throughout the house and aiding in dehumidification.

06. Make sure your window air conditioner is the proper size. It's better to get one that's too small than too large - a larger unit will start up and turn off more frequently and won't do as good a job dehumidifying the air.

07. Don't judge the efficiency of your air conditioner by the sound of the fan shutting on and off. The blower will continue to circulate cooled air throughout your home up to 15 minutes after the compressor has stopped. (The same holds true for the furnace.)

08. Raise the thermostat to about 78 to 80 degrees whenever you go to bed or leave the house. A programmable thermostat will do this for you automatically.

09. If your home can't accommodate central air conditioning, try a whole-house attic fan. This device pushes hot air out through attic vents, lowering the temperature throughout your home about five degrees in less than ten minutes. Attic fans cost less than 25 cents per day to operate.

10. During the winter, remove window air conditioners and seal the windows with caulk and weatherstripping. You might also want to cover the central air compressor with a tarp to keep it clean.

Electricity

Don't Heat - or Cool - the Great Outdoors!

Americans use twice as much energy as necessary to heat their homes. That accounts for a lot of wasted energy!

If you have a fireplace, close the damper when you don't have a fire burning. An open fireplace damper can let 8 percent of heat from your furnace escape through the chimney! In the summer, an open fireplace damper can let cool air escape. It's like having a window open!

Make a map of your home, and mark all the windows, heating vents, and outside doors. Take a ribbon and hold it up to the edges of the doors and windows. If the ribbon blows, you've found a leak! Ask Mom or Dad to seal the leak with caulk or weatherstripping.

Think about your curtains. Keeping the curtains closed on cold, cloudy days helps block the cold outside air from getting inside. Also, keeping the curtains closed on very hot days keeps the hot air out!

In the Bedroom

Turn off your electric blanket when you aren't in bed.
Don't leave on your computer, TVs, radios or games that use electricity when you're not using them.

In the Bathroom

Wasting water wastes electricity. Why? Because the biggest use of electricity in most cities is supplying water and cleaning it up after it's been used!

About 75 percent of the water we use in our homes is used in the bathroom. Unless you have a low flush toilet, for example, you use about five gallons to seven gallons of water with every flush! A leaky toilet can waste more than 10,000 gallons of water a year. Wow!

Drippy faucets are bad, too. A faucet that leaks enough water to fill a soda bottle every 30 minutes will waste 2,192 gallons of water a year.

Another simple way to save water AND energy is to take shorter showers. You'll use less hot water - and water heaters account for nearly 1/4 of your home's energy use.

In the Kitchen

According to researchers who are paid to study such things, a load of dishes cleaned in a dishwasher uses 37 percent less water than washing dishes by hand! However, if you fill up one side of the sink with soapy water and the other side with rinse water - and if you don't let the faucet run - you'll use half as much water as a dishwasher does. Doing the dishes this way can save enough water for a five-minute shower!

If you need to warm up or defrost small amounts of food, use a microwave instead of the stove to save energy. Microwave ovens use around 50 percent less energy than conventional ovens do. For large meals, however, the stove is usually more efficient. In the summer, using a microwave causes less heat in the kitchen, which saves money on air conditioning.

Don't keep the refrigerator door open any longer than you need to. Close it to keep the cold air inside! Also, make sure the door closes securely. There is a rubber-like seal around the door that you can test. Just close the door on a dollar bill, and then see how easy it is to pull out. If the dollar slides out easily, the door is probably leaking cold air from inside.

Is there an old refrigerator sitting in the garage or someplace else at home? Old refrigerators are real energy hogs! An old refrigerator could be costing your family as much as $120 a year to operate. Urge your parents to replace it if they don't need it, and remind them that one large refrigerator is cheaper to run than two smaller ones.

Don't Leave Things Turned On
Turn off the TV when no one is watching it. The same goes for computers, radios and stereos - if no one using it, turn it off. Turn off all the appliances at the surge protector/control strip - that four- or six-plug extension chord that you plug all your computer things into. Some devices, like modems or other networking boxes are drawing small amounts of power all the time. Check with your folks first, but the best thing to do is turn them ALL off at the surge protector.

Energy Efficient Bulb

Compact Fluorescent Lights (CFL) and Light Emitting Diode (LED) bulbs have revolutionized energy-efficient lighting.
CFLs are simply miniature versions of full-sized fluorescents. They screw into standard lamp sockets, and give off light that looks just like the common incandescent bulbs - not like the fluorescent lighting we associate with factories and schools.

LEDs are small, solid light bulbs which are extremely energy-efficient. New LED bulbs are grouped in clusters with diffuser lenses which have broadened the applications for LED use in the home.

Benefits

Efficient: CFLs are four times more efficient and last up to 10 times longer than incandescents. A 22 watt CFL has about the same light output as a 100 watt incandescent. CFLs use 50 - 80% less energy than incandescents.
Less Expensive: Although initially more expensive, you save money in the long run because CFLs use 1/3 the electricity and last up to 10 times as long as incandescents. A single 18 watt CFL used in place of a 75 watt incandescent will save about 570 kWh over its lifetime. At 8 cents per kWh, that equates to a $45 savings.
Reduces Air and Water Pollution: Replacing a single incandescent bulb with a CFL will keep a half-ton of CO2 out of the atmosphere over the life of the bulb. If everyone in the U.S. used energy-efficient lighting, we could retire 90 average size power plants. Saving electricity reduces CO2 emissions, sulfur oxide and high-level nuclear waste.
High-Quality Light: Newer CFLs give a warm, inviting light instead of the "cool white" light of older fluorescents. They use rare earth phosphors for excellent color and warmth. New electronically ballasted CFLs don't flicker or hum.
Versatile: CFLs can be applied nearly anywhere that incandescent lights are used. Energy-efficient CFLs can be used in recessed fixtures, table lamps, track lighting, ceiling fixtures and porchlights. 3-way CFLs are also now available for lamps with 3-way settings. Dimmable CFLs are also available for lights using a dimmer switch.

Reusable Bags for Grocery Shopping

The new Wal-Mart shopping bags are made from a fabric containing rPET. The bags are made from 85% recycled content and hold more than twice the amount of an average plastic bag. The bags are sold for $1 and be located near checkout aisles in Wal-Mart stores. Wal-Mart also take the bags back at the end of their life-span for recycling. Give it a shot next time you go grocery shopping.. you will be surprised how many small things you can put in that Black reusable bag.

Carbon Dioxide Concentration (ppm)

Carbon Sequestration using trees

Carbon dioxide is a potent greenhouse gas and a major contributor to climate change. Carbon Sequestrating indicate storing carbon in trees which are then turned into Organic Carbon through photosynthesis. This carbon is also stored in plant tissues. Thus furniture made from wood store carbon for a long time.
There are three types of Sequestration,
1. Biological Sequestration
2. Geological Sequestration
3. Ocean Sequestration

Carbon intake has been estimated and below are some quantitative data which can give a clear idea of how effective this can be.
25 year old deciduous tree – sequesters 2.52 lbs of CO2 annually
120 year old deciduous tree – sequesters 5.58 lbs of CO2 annually

25 year old evergreen tree – sequesters 14 lbs CO2 annually
120 year old evergreen tree – sequesters 11.7 lbs CO2 annually
(Figures generated by Tufts (University) Climate Initiative)

Some people believe planting trees just for the purpose of Sequestration could reduce the amount of CO2 in the atmosphere. But an article published in Duke University says, the Carbon Sequ. can cause water and nutrient depletion and increased soil salinity and acidity as side effects over decades. Read more about this.

But that doesnt mean we should stop planting trees. Planting trees as much as we can will help us reduce Carbon levels and delay the changes in Climate if not change it back to before...

Save the Earth; welcome to enV

Trees are the main source that hold animal civilizations. So protect it and will live longer... Recent years as human population increases, consumption of fuel resources has been depleting. Need for alternative energy sources are high. Depleting energy (Fuel) makes fuel prices sky rocket over past 6 months period. Earth possesses limited amount of resources.. when run out human civilization will have difficulty running... Thus saving the earth and using energy efficiently is vital in today's world.
