Reduced Emissions From Electricity Generation
A recent report from the Energy Information Administration notes that for the first time in 40 years, carbon dioxide emissions from electricity generation are less than those from transportation. The reason is that power plants nationwide are abandoning the use of coal and turning to cleaner burning natural gas, as well as newer sources such as solar and wind power.

A Big Wind Farm for New York
The Board of Trustees of the Long Island Power Authority has voted to approve the nation’s largest offshore wind farm, which is also the first offshore wind farm in New York. The South Fork Wind Farm, located 30 miles southeast of Montauk, New York, will be a 90 megawatt facility that will provide enough electricity to power 50,000 Long Island homes and help meet increasing electricity demand on the South Fork of Long Island.
2016 Carbon Progress Report
Last year was a big year for progress in the U.S. power sector. Renewable energy provided nearly 17% of the country’s electricity, up from 13.7% in 2015. The first offshore wind farm in the U.S. opened off the coast of Rhode Island. And most significantly, carbon emissions from the power sector continued to decline and reached the lowest levels in nearly 25 years.
Energy From Jellyfish
Jellyfish are fascinating in appearance but generally are nothing but trouble. Their stings can ruin a tropical vacation but they can cause far more damage than that.
Cheap Wind And Solar Power
Multiple studies are now reporting that wind and solar power are the cheapest way to make electricity in a growing number of places around the world. A thorough analysis of the levelized cost of energy – which considers every cost component from capital expenditures to operating and maintenance costs over a lifetime – shows that solar and wind power are winning the day.
Clean Power Is Cheap Power
There are many good reasons why we should be making the transition from fossil fuel energy sources but the one that is likely to be the most persuasive is strictly economic. It has long been said that the renewable energy future will truly arrive when installing new solar panels is cheaper than a comparable investment in coal, natural gas, or other options.
Is Coal Coming Back?
The new administration has promised to revitalize the coal industry in the U.S. A major part of this plan is to eliminate various regulations that hamper that industry. But the truth is that coal has lost ground for far more important reasons than regulation.
Storing Energy In An Old Mine
An abandoned, centuries-old iron mine in the Adirondacks about 100 miles north of Albany, New York may become the site of a new hydroelectric energy storage system. The mine in the tiny hamlet of Mineville near Moriah, New York contributed iron for the first naval battle of the Revolutionary War that took place on Lake Champlain. The mine hasn’t been used in over 45 years.
More Renewables On Campus
We recently talked about the increasing efforts by colleges and universities to embrace sustainability with the use of renewable energy sources. Those efforts are increasing in many places.
Solar Power And African Food Security
Some of the poorest countries in the world are unfortunately among the most vulnerable to the effects of climate change. Malawi, for example, has 90% of its population in rural areas and 80% of its labor force is associated with agriculture.
Building A Better Solar Cell
The great majority of solar cells being manufactured today are based on silicon crystals. That technology has come a long way over time and has gotten cheaper and more plentiful as the industry has grown.
Renewables On Campus
Colleges and universities across the country are increasingly deploying solar arrays and other types of renewable energy. Many have set goals to become carbon neutral.
Floating Wind
Offshore wind power can supply a significant amount of energy to our hungry grid. In many places in Europe, it is doing just that. Here in US, it is just starting to be used in some places in the Northeast, with the first small offshore wind farm coming on line off the coast of Rhode Island.
Student-Led Solar Revolution
College students have often spearheaded uprisings and revolutionary ideas. A group of BYU engineering students is trying to start a solar-cell revolution.
Offshore Wind In Europe
The U.S. has just turned on its first offshore wind farm off the coast of Rhode Island. In the meantime, offshore wind continues to grow by leaps and bounds in Europe. Wind energy in the European Union accounts for 12% of its electricity supply. Until 2011, offshore wind comprised only 5-10% of the newly-installed wind energy capacity; now it about one third of the new installations.
Renewable Energy As Art
When we think about the visual impact of energy plants, we usually envision ugly smokestacks belching out toxic fumes. Of course, many people also consider wind turbines to be eyesores and even solar panels are often viewed unfavorably from an aesthetic point of view.
Energy At Our Feet
There are both big ideas and small ideas for generating electricity from renewable sources. For example, even though there are now gigantic solar energy farms producing vast amounts of electricity, there are also plans to embed solar technology in the windows of homes and businesses to capture even more of the sun’s energy.
Kite Power
Wind power is a growing contributor to the energy grid but it has its limitations. Wind turbines need to be located in windy places and the structures are big, get in the way of things, and are rather costly.
Turning Sunlight into Fuel
When looking at the best ways to meet humanity’s energy needs, there is little doubt that the sun is the ultimate answer. In one hour, the Earth receives enough energy from the sun to meet all of our needs for a year. Despite this fact, the world currently only gets about 1% of its energy directly from the sun.
