Electric cars represent only a tiny fraction of the overall auto market. The numbers are growing, most certainly, but they are still quite small in most places. The recent start of production of the Tesla Model 3 has attracted quite a bit of attention to electric cars, but in many countries, there is much more to the story than just media buzz about a new car.
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.
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.
Offshore wind farms are becoming increasingly important around the world. Europe has thousands of wind turbines off its coasts generating more and more of its power. The first offshore wind farm in the U.S. opened for business last year and more are on the way.
Electric cars have been around for a long, long time. The first ones appeared in the mid-19th century. Around the turn of the 20th century, they were popular for taxi cabs in places like New York City. But within about 10 years, they mostly disappeared. In the 1990s, electric cars had a brief revival with vehicles like the General Motors EV1. But again electric cars mostly vanished.
Terrible traffic in cities around the world is a real blight on urban life. Increasingly, there are many cities where you simply don’t want to have to go anywhere by car during morning and evening rush hours.
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.
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.
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.
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.
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.
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.
The Paris Climate Agreement seeks to reduce global carbon emissions. The nearly 200 countries who signed it have pledged to reduce their own emissions within their borders. And therein lies the rub: the agreement says nothing about the impact their products have across the world. For some countries, the problem is not so much the emissions they produce; it is those they export.
Trees are nature’s way of removing carbon dioxide from the atmosphere. Growing plants take up CO2 and store it in the form of their roots, stems and leaves. And in fact, a significant factor in the growing levels of carbon dioxide in the atmosphere has been the extensive deforestation that has gone on over the past couple of centuries.
The world’s largest floating solar power plant is now operational and connected to the electric grid in China. It is a 40-megawatt facility and floats in water 13 to 30 feet deep in a lake that was created by a former mining operation.
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.
A new carbon capture plant, sitting on top of a waste incineration facility near Zurich, Switzerland, is now sucking CO2 out of the air to sell to its first customer. The plant opened on May 31, and is the first commercial enterprise of its kind.
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.
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.
