The Perils Of Air Conditioning

September 12, 2017 By EarthWise

The Perils Of Air Conditioning https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-12-17-The-Perils-of-AC.mp3

The battle to reduce greenhouse gas emissions is heavily focused on replacing fossil fuel power plants with renewable energy and replacing internal combustion engine autos with electric cars.  But there is another elephant in the room:  air conditioners.

A Faster Car Battery

A Faster Car Batteryhttps://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-11-17-A-Faster-Car-Battery.mp3

There is more and more interest in electric cars and, based on the half million advance orders for the Tesla Model 3, more and more of us plan to be driving them.  For many of us, the technology is already good enough to meet most if not all of our motoring needs.

Air Pollution And Solar Powerhttps://earthwiseradio.org/wp-content/uploads/2017/07/EW-07-28-17-Air-Pollution-and-Solar-Power.mp3

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.

A New Record For Solar Hydrogen Production

A New Record For Solar Hydrogen Productionhttps://earthwiseradio.org/wp-content/uploads/2017/05/EW-05-29-17-A-New-Record-for-Solar-Hydrogen-Production.mp3

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.

Spray-On Solar Cells

Spray-On Solar Cellshttps://earthwiseradio.org/wp-content/uploads/2017/04/EW-05-15-17-Spray-On-Solar-Cells.mp3

One of the most exciting possibilities for future solar energy technology is that of solar cells that can be sprayed or printed on to surfaces like the windows of skyscrapers, the roofs of sports utility vehicles, or the walls of houses.  And the expectation is that such technology would be far cheaper than today’s silicon-based solar panels.

Hydrogen On Demand

Hydrogen On Demandhttps://earthwiseradio.org/wp-content/uploads/2017/04/EW-04-28-17-Hydrogen-on-Demand.mp3

Researchers at the Technion-Israel Institute of Technology have developed a new method for producing hydrogen from water using solar energy.  If successfully developed, their approach would make it possible to produce hydrogen in a centralized manner at the point of sale such as at a fueling station for hydrogen-powered cars.

American Cities Fighting Climate Change

American Cities Fighting Climate Changehttps://earthwiseradio.org/wp-content/uploads/2017/04/EW-04-24-17-American-Cities-and-Climate-Change.mp3

The federal government now appears to be headed down the path of not honoring America’s commitments to tackle global warming, but many of the country’s cities and states as well as its corporations have no intention of breaking our promises to the world.

Livestock And Antibiotics

Livestock And Antibioticshttps://earthwiseradio.org/wp-content/uploads/2017/01/EW-01-19-17-Livestock-and-Antibiotics.mp3

According to the FDA, approximately three-quarters of all antibiotics used in the U.S. are fed to livestock for non-therapeutic purposes.  This routine administration of antibiotics promotes the development of antibiotic-resistant bacteria, which can spread to animals and humans.   And as antibiotic-resistant bacteria spreads, medicines used to treat human diseases can become less effective. Antibiotic resistant infections kill 90,000 Americans each year.

Using Less Energy

Using Less Energyhttps://earthwiseradio.org/wp-content/uploads/2016/12/EW-12-19-16-Using-Less-Energy.mp3

Americans comprise less than 5% of the world’s population, but we use almost 20% of its energy.  This is a problem from many perspectives and it is one that we are at least trying to solve.

Virtual Power Plants

Virtual Power Plantshttps://earthwiseradio.org/wp-content/uploads/2016/09/EW-09-22-16-Virtual-Power-Plants.mp3

The traditional model of the electricity grid is one where centralized large power plants send power through transmission lines to substations and then on to homes and businesses.  As localized renewable energy sources, energy storage systems, and efficiency systems proliferate throughout the system, a new concept is emerging:  that of the virtual power plant.

Growing More Food On Less Land

Growing More Food On Less Landhttps://earthwiseradio.org/wp-content/uploads/2016/05/EW-05-06-16-Growing-More-Food.mp3

There are predictions that the world’s population could reach 10 billion by the year 2050.  Whether population growth can be slowed down enough to prevent this remains to be seen.  Regardless, it is clear that we need to figure out how to feed many more people than we have today and we are not even doing that good a job of feeding the current population.
