France And Climate Change
On the heels of the Trump Administration’s decision to withdraw from the Paris Climate Accord, France has rolled out ambitious plans to reduce its carbon footprint even further.
New York Steps Up
Now that the Trump administration announced that the United States would cease implementation of the Paris Climate Agreement, various state, local and corporate entities in this country have been stepping up to assume climate leadership.
Sustainable Ethanol
Most gas stations in the U.S. sell a blend of 90% gasoline and 10% ethanol. Mandated by legislation, the 14 billion gallons of ethanol consumed annually by American drivers is mostly made from fermented corn. Producing this ethanol requires millions of acres of farmland.
New Milestones For Renewable Energy
There is no question that solar power has been growing by leaps and bounds in recent years, but whenever one really looked at the numbers, it seemed to still be only a tiny fraction of the country’s power generation – until quite recently, less than one percent.
A Record Drop In Coal Consumption
Global consumption of coal dropped by 1.7% last year. This is a major change considering that it had increased by an average of 1.9% per year from 2005 to 2015. China, which accounts for about half of the coal burned in the world, used 1.6% less in 2016, as compared to an increase of 3.7% per year over the previous 11 years.
A Microgrid in New York’s Capital
New York State has been encouraging its communities to install microgrids for quite a while. Now the state has committed to build a 16-megawatt microgrid to power the Empire State Plaza in downtown Albany. The microgrid will use combined heat and power to supply 90% of the electricity as well as heating and cooling for the 10 buildings where 11,000 state employees work.
Air Pollution And Solar Power
We are well-aware of the negative effects of air pollution on human health and on the environment, but a recent study at Duke University has revealed that global solar energy production is taking a major hit due to air pollution and dust.
Offshore Wind Progress
Last December, the first commercial offshore wind farm in the United States started operation off the coast of Rhode Island. The Fisherman’s Energy Atlantic City Windfarm off the coast of New Jersey is under construction. With the lengthy logjam finally broken, there is increasing activity in the emerging U.S. offshore wind sector.
Clean Air And Energy
Researchers in Belgium have engineered a device that uses sunlight to purify polluted air and, in the process, produces hydrogen gas that can be stored and used for power. Two teams of researchers separately investigating processes for air purification and hydrogen production combined their efforts to create the new device.
Fern-Inspired Energy Storage
The amount of solar energy striking the surface of the earth in two hours is enough to supply all of humankind’s needs for an entire year. For this reason, it is widely thought that solar energy should be our primary source of electricity. If this is to happen, however, there must be cost-effective ways to obtain solar electricity regardless of the time of day, weather, or seasonal changes. Essentially, there must be ways to store the energy from the sun to use it when we need it.
China And India Climate Progress
China and India have 36% of the world’s population and produce about 35% of global CO2 emissions, ranking first and third respectively in that category. The United States, with a little over 4% of the world’s population, produces about 16% of global CO2 emissions, good for second place.
An Aluminum Battery
The battery industry is currently dominated by lithium-ion batteries. We have them in our phones and computers. They power electric cars. And they are increasingly being used to store energy generated by solar panels and other renewable energy sources.
Improving Energy Storage
The transition to sustainable energy sources faces many challenges. One important one is to make those sources as reliable as conventional energy systems. For technologies like solar and wind power, which can’t operate around the clock, an enabling element is effective energy storage. Energy storage is critical for both the electricity grid and for transportation.
Surging Wind Power In The U.S.
So far, it has been a big year for the U.S. wind industry, which experienced its fastest first-quarter growth since 2009. In total, about 2,000 megawatts of new capacity was installed, enough to power about 500,000 homes. With this addition, wind now produces 5 1/2% of the country’s electricity.
Fossil Fuel Companies And Renewables
There is a tendency to think of the changes in the energy industry as a pitched battle between fossil fuel companies and renewable energy. There is some truth to this, but only to a certain extent. The multi-trillion-dollar fossil fuel industry is made up of businesses dedicated to growth and increased profits. And like businesses in other industries when major changes occur, fossil fuel companies may read the tea leaves and change with the times.
Renewable Energy Projects In The Northeast
The seven northeastern U.S. states that make up the Regional Greenhouse Gas Initiative have all set ambitious emissions reduction goals and renewable energy targets that will be difficult to meet. For example, New York has the goal of getting 50% of its electricity from renewable sources by the year 2030.

A New Record For Solar Hydrogen Production
Renewable energy may be under attack by the federal government these days, but one federal agency is making great progress on using the sun’s energy to split hydrogen from water. The National Renewable Energy Laboratory, located in Golden, Colorado, recently highlighted two initiatives aimed at the production of renewable hydrogen.
