A Hydrogen Sponge

April 7, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/04/EW-04-07-17-A-Hydrogen-Sponge.mp3

Hydrogen fuel cell electric vehicles are just starting to enter the market but they have a long way to go before they can even catch up with their battery-powered counterparts. Powering cars with hydrogen has the advantage that fueling the vehicle is much like what we are used to:  pull up to the pump, fill your tank for a few minutes, and drive off.

New York’s Solar Boom

April 4, 2017 By EarthWise

New York Governor Andrew Cuomo recently announced that the state’s support for solar power initiatives has resulted in an 800% increase in industry growth since 2011.   New York’s various renewable energy programs have resulted in $1.5 billion in investments.  The NY-Sun Initiative has produce a 10-fold increase in solar projects in several regions of the state.  The Mohawk Valley led the way with an almost 16-fold increase in solar capacity.

Islands Ditching Diesel

Islands around the world have a difficult time developing the infrastructure for electricity generation.  Many are simply too small or too poor for conventional power plants.  The most common electricity source on islands is diesel generators which are not environmentally friendly and result in some of the most expensive electricity in the world.

Solar Power In China

March 27, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/03/EW-03-27-17-Solar-Power-in-China.mp3

Installations of solar power continue to increase rapidly around the world and in no place more than China.  By the end of 2016, total solar generating capacity in China reached 77.4 gigawatts, making it the largest producer of solar energy in the world.  Globally, there is a total of 228 gigawatts of solar power installed, although that number keeps changing rapidly.

Volcano Power

Geothermal energy uses the heat trapped beneath the Earth’s surface to generate electricity.  Typically, geothermal energy plants tap into the steam from natural sources such as geysers, or they draw water from hot, high-pressure underground sources.  The hot vapors are then used to drive electric turbines.

High levels of an element found in coal ash have been detected in fish in two lakes where Duke Energy coal-fired power plants are located, according to a peer-reviewed study at Duke University. The element, selenium, occurs naturally but is concentrated in coal ash.

A New Low-Cost Battery

March 15, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/02/EW-03-15-17-A-New-Low-Cost-Battery.mp3

Batteries have never been more important.  Not only do we all depend on cell phones, tablets and laptop computers that run on batteries, but two enormous industries are in major transitions that rely upon battery technology: personal transportation and the utility industry.   The electricity grid is increasingly turning to solar and wind power for generation and both will require effective energy storage if they are to truly become the predominant sources of electricity.

https://earthwiseradio.org/wp-content/uploads/2017/02/EW-03-10-17-The-Largest-Battery-Storage-Substation.mp3

At the end of last year, Southern California Edison turned on the largest lithium-ion battery storage facility in the world in Ontario, California.   It is a substation with 80 megawatt-hours of capacity, enough energy to power 2,500 households or charge 1,000 Tesla cars a day.

https://earthwiseradio.org/wp-content/uploads/2017/03/EW-03-08-17-The-Success-of-SunShot.mp3

Back in 2011, utility-scale solar power cost a little over $4 per watt on average.  In February of that year, former Energy Secretary Steven Chu announced the SunShot initiative, which had the goal of reducing the total cost of photovoltaic systems by 75% to the target value of $1 a watt by the year 2020.

From melting Arctic ice to dying coral reefs to rising sea levels, there was no shortage of grim environmental news in 2016.  But the news wasn’t all bad.  There were several bright spots for the environment last year as well.

Reduced Emissions From Electricity Generation

February 28, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/02/EW-02-28-17-Reduced-Emissions-from-Electricity-Generation.mp3

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

February 27, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/02/EW-02-27-17-A-Big-Wind-Farm-for-NY.mp3

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

February 22, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/02/EW-02-22-17-2016-Carbon-Progress-Report.mp3

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.

February 1, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/02/EW-02-01-17-Cheap-Wind-and-Solar-Power.mp3

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

January 31, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/01/EW-01-31-17-Clean-Power-is-Cheap-Power.mp3

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?

January 23, 2017 By EarthWise

https://earthwiseradio.org/wp-content/uploads/2017/01/EW-01-23-17-Is-Coal-Coming-Back.mp3

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

https://earthwiseradio.org/wp-content/uploads/2017/01/EW-01-20-17-Storing-Energy-in-an-Old-Mine-1.mp3

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.
