A Battery That Eats Carbon Dioxide
Fossil fuel-based power plants are increasingly considering the use of carbon capture technologies as a way to reduce emissions. The biggest challenge to the wide-spread adoption of such technology is its energy cost, which of course equates to economic cost. Present-day power plants equipped with carbon capture systems can use up to 30% of the electricity they generate just to power the capture, release, and storage of carbon dioxide.
Robo-Taxis And The Grid
The world of personal transportation is evolving. There are three trends that are developing at the same time: cars running on electricity rather than fossil fuels, cars operating autonomously, and people sharing vehicles instead of owning them.
The Earliest Overshoot Day Ever
Earth Overshoot Day marks the date when humankind’s demand for ecological resources and services in a given year exceeds what our planet can regenerate in that year. The deficit for the remainder of the year means we are liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere.
A Million Electric Cars
Last year, China was the first country to reach the milestone of having one million electric cars. This year, China will add another million plug-in vehicles. Of course, with its huge population, China sells four times as many cars in total per year as any other country.
Emissions From Electric Buses
Municipalities and transit agencies are gradually replacing conventional diesel buses with cleaner alternatives such as natural-gas-powered, diesel-electric hybrid, or fully electric buses. The goal is to reduce the substantial carbon emissions associated with buses as well as reducing unhealthy air pollution. Diesel buses on average get less than 5 miles per gallon as they transport passengers around, so there is plenty of motivation to find more efficient ways to power them.
Hoover Dam As A Giant Battery
Back in the 1930s, building Hoover Dam was a public works project likened to the pyramids. Hoover Dam helped transform the American West, harnessing the force of the Colorado River to power millions of homes and businesses.
Global Warming And Air Conditioners
All those record high temperatures around the world this summer – such as during the unprecedented heatwave in Japan – put the spotlight on the growing dependence we all have on air conditioning.
Greener Concrete
The battle to reduce carbon emissions is heavily focused on electricity generation, transportation, buildings, and agriculture, which collectively account for more than 75% of the total. However, there are other sources of carbon emissions that cannot be ignored. Among industrial activities, the production of cement is responsible for 7% of industrial energy use and is the second largest industrial emitter of carbon dioxide. Making cement accounts for about 7% of global emissions.
A Battle For The Automobile Fuel Business
Energy giant BP predicts that electric vehicle sales will increase by an incredible 8,800 percent between now and 2040. That creates a major business opportunity for oil companies as well as a real problem because demand for gasoline and diesel is destined to slow.
