As the fastest growing fossil fuel, coal has added almost as much to the world’s absolute energy supply in the last ten years as all other sources combined. Burned gratuitously by the gigaton, coal power plays a dominant and still-growing role in generating the world’s electricity.
(Picture Credit-Coal miner Lee Hipshire in 1976, shortly after emerging from a mine in Logan County, W.Va., at the end of his shift. A few years later, Lee took early retirement because of pneumoconiosis, or black lung disease. He died at 57.)
Coal is a widely distributed energy resource. Reserves can be found on every continent aside from Antarctica, although they are heavily concentrated in a handful of nations.
The countries with the largest known reserves are the United States, China and Russia, collectively possessing about half of the world’s recoverable tonnage. These three—along with Germany, India and Australia—account for about eighty percent of economically viable deposits globally.
The United States has far more underground than (Read More....)
The demand for greener home goods is rapidly growing, and air conditioners are no exception. When remodeling a home or purchasing a new appliance, most homeowners seek the newest efficient, environmentally friendly models. These new products are safer for the environment and they use less energy, which means homeowners are left with a lower energy bill.
Why are Older Models Harmful for the Environment?
Old models of air conditioners used a type of CFC coolant now known to cause serious damage to the ozone layer. For that reason, newer air conditioning systems use different coolants. While even the newest air conditioners may have an adverse effect on the climate (according to the New York Times, despite the switch to refrigerants that have less of an effect on the ozone layer, gasses produced by new air conditioners still affect climate change), homeowners looking to go “green” will be happy to make do with the newest technology available.
At the very least, air conditioners are far greener now than they have ever been. For those who live in a hot climate, living without air conditioning is a (Read More....)

The world’s farm land appears to be turning into deserts. With all of our science and all of our learning on crops, why?
I think it is because of the dismissal of rules of common sense and from the Bible.
Factory farms are just plain wrong.
The Bible basically states we should rotate crops. Those crops should rotate and land should be allowed to recover once every seventh year. That means letting it grow wild on the seventh year.
Every once in a while we need to have a Jubilee year where everything goes back to the way it started.
Basically that is what the Bible says. To me it is a handbook on how to run Planet Earth.
When you go against the basics, then things fall apart.
The biggest failed experiment in history was the use of land prior to the great depression of the 30s. The result was a wrecked ecology. The dust storms of Oklahoma need no comment.
We have gotten away from those basics with the factory farms. Factory farms are not efficient, contrary to what people (Read More....)
Over the past few years, environmentally friendly cars have become more affordable for the average American. While there have been many improvements recently in green technology, car manufacturers still have a long way to go before they can produce a car that is one hundred percent free of fossil fuels.
Since natural gas hit the car market eleven years ago, the number of natural gas vehicles in use today exceeds eight million around the world. Tighter government emissions standards and pressure that’s being put on manufacturers has helped the natural gas movement come a long way. This is especially true in the semi-truck industry.
Low carbon fuel technology is now being used in semi-trucks and has been estimated to emit as much as thirty percent less greenhouse gas than diesel. Because manufacturing costs have been severely reduced due to the large expansion of natural gas vehicle production, green-friendly semi-trucks are becoming more affordable. This is good news for truck drivers and transportation companies alike because current fuel costs show that CNG costs as (Read More....)
LEED certification (Leadership in Energy and Environmental Design) is an invaluable asset to any new construction project. This building rating system standardizes the characteristics of buildings that ensure it is efficient, environmentally friendly, and provides a safe atmosphere for employees or residents. This independently applied certification was developed by United States Green Building Council but is now being put into practice across the entire globe. Buildings that score well within this system use green products and technology from the roof down to the individual nails. High ratings increase property value, lessen the total costs of construction, and reduce the amount of energy necessary to regulate the internal environment.
What Can Roofing Do?
Green roof designs can vary widely from building to building. However, the LEED certification standards have been designed around allowing buildings to earn credits based on the most critical aspects of efficiency that are related to typical green roofing projects. Many green roofing systems will take advantage of vegetative (Read More....)
