Ethanol made from corn starch sources requires a sizable amount of farmland resources as close to two-thirds of the total corn cultivated is dedicated to produce ethanol for biofuel and animal distillers grains [refer to National Corn Growers Association].
In other words it requires close to 60 million acres of farmland dedicated mainly for ethanol production in order to manufacture around 15 billion gallons of ethanol per year, which is about the amount needed to fulfill ethanol as a 10 % by volume fuel additive to gasoline. It is claimed that ethanol is needed as an oxygenated fuel additive in order to raise the octane number of the fuel and reduce carbon monoxide emissions.
In addition, world wide organizations have asserted that corn production in the United Stated for the main purpose of providing it as a fuel additive to gasoline has caused world food prices to rise dramatically and has also contributed to world food shortages. It is asserted then that the US should come up with alternative renewable fuel production methods that would not compete with the food supply but also be energy efficient in method too.
This essay is dedicated to show that there are alternative alcohol production methods available not only for ethanol but also for higher molecular weight alcohols.… Read More
The number of people acquiring solar panels for the home has been increasing gradually.
This is being driven by the desire to have green or cleaner energy. Solar energy is also renewable and does not pollute the environment. However, the uptake of solar panels especially in the home is still quite low. This is being experienced despite the mass campaigns.
The following are some reasons why investing in a solar panel is beneficial:
Great strides have been made in solar panel technology. A few years back, the photovoltaic panels were not very strong. Actually, many would rarely last for more than 10 years. However, modern panels are quite sturdy. They feature stronger material and designs. Most of the solar panels found today can easily last for 40 to 50 years.

Solar Energy: The ultimate energy source
It provides the earth with light, heat and radiation. Every hour the sun radiates onto the Earth more than enough energy to satisfy global energy needs for an entire year.
When sun’s energy is harnessed and made useable it is called solar energy. While many technologies derive fuel from one or the other from form of solar energy, there are also technologies that directly transform the sun’s energy into electricity.
Solar energy is our earth’s core source of renewable energy since generating electricity directly from sunlight does not deplete any of the earth’s natural resources and supplies the earth with energy continuously.
Solar energy generating electricity
Photovoltaic devices produce electricity when sunlight strikes them. Electricity generation relies upon chemical. When sunlight strikes a PV cell, chemical reactions release electrons, thus generating electric current. Using PV is a cheaper option than new electric lines for providing power to remote locations.
Solar Power Plants – generates electricity when the heat from solar thermal collectors is used to heat a fluid to produces steam that is used for power generation. Use the sun’s heat to generate steam to drive an electric generator.

Climate change isn’t just about a few degrees variation
The Earth’s environment is changing faster than we can possibly predict the consequences. The debate is not whether changes are coming but how severe they’ll be.
Global warming is the gradual raise in temperature of the Earth’s surface that has aggravated considerably since the industrial revolution. Over the past two decades the effect has become more than noticeable. The global average temperature has increased 14 to 18 degrees C since the late 1800’s. Many experts estimate an additional 14 to 18 degree rise in the average temperature during the next 100 years.
We have upset the balance

Benefit Your Health and Preserve Planet Earth
The definition of “green living” is something more than choosing paper instead of plastic grocery bags, recycling beer cans and newspapers, driving a fuel efficient car, eating organically grown food.
These activities certainly contribute to keeping our planet Earth and our personal health in good shape… But understanding “green living” and what exactly does it have to do with improving personal health and energy brings us to a broad definition of green living: Green Living is any action or activity that results in a positive impact, to any degree, on the environment so that the planet can continue to support the generations to come.… Read More
If you are environmentally aware and you plan on taking full responsibility for your own actions that may be affecting the environment, then buying yourself some carbon offsets is the best new option.
But if you plan on buying some carbon offset, then here are the things that you first need to look at before you start looking for a provider.
Firstly, you need to figure out what the sources are in your life for the emission of carbon dioxide. For the average man in America, the most common source of carbon Dioxide emission in your daily life has to be your driving the car or any other vehicle. There are other ways which might be sources for carbon dioxide emissions as well, for example many household products emit carbon dioxide on their use and even traveling by air will add up to that. Firstly, you must calculate your carbon footprint. This is how much total of carbon dioxide you cause to the environment through your daily activity. In fact you can just try out one of those online carbon footprint calculators that will just make your job of finding out your carbon footprints easier.… Read More
Recycling glass is a simple and cost efficient way to help the environment that is also super beneficial.
The point is that if you throw away a bottle made of glass and you sit comfortably thinking it is being taken care of in the landfill, it is actually not the case.
That glass bottle will easily take up to a million years to actually break down. Till then it would just be polluting the environment constantly. However, in contrast to that if you recycle that bottle of glass then within a month that same glass will be used somewhere else serving a better purpose.… Read More
If you really want to do your part for the environment you really do not have to take too much trouble on a daily basis to keep that promise to yourself.
In fact there are some very easy daily things that you can maintain and thereby do your bit for the environment.
- Reduce, Reuse, Recycle: this is a very easy concept. All you have to do to reduce waste and thus reduce environmental pollution is to reuse as many things as possible.Also, recycling those things that are recyclable is the best that you can do to reduce pollution.
- Avoid heat and air condition: you do not have to live in sweltering heat or the bitter cold for this, just to avoid using the heater and the air conditioner. You could simply install insulation in your wall or weather strips to help do the job for you.
- Use the right light bulb: Compact Fluorescent light bulbs are the most environmental friendly and so try changing the regular light bulbs that you use for those. These bulbs give out very little heat and also consume little energy.
- Drive as little as possible: avoid driving to short distances, especially to places where you can make it on foot itself. The lesser you use an automobile, the lesser would be

The American Wind Energy Association welcomed the announcement from the U.S. Departments of the Treasury and Energy, about the Administration has begun issuing renewable energy grants under a program approved by Congress in the economic recovery package earlier this year. The announcement included grants of nearly $500 million for 10 wind power projects in Maine, Minnesota, New York, Oregon, Pennsylvania and Texas.
“For these grantees and many other projects that are preparing their applications, we are seeing business activity picking up and turbine and parts orders being sent all the way up the value chain,” commented AWEA Senior Vice President for Public Policy Rob Gramlich, adding, “That activity had all but dried up and it is very encouraging to see this turnaround underway. Time will tell if that market signal is strong enough to keep the 85,000 people working in the wind industry employed for the next couple of years.”… Read More
