Cleaning Britain’s Air
According to a new study by the non-profit group Carbon Brief, carbon dioxide emissions in the United Kingdom are at their lowest levels since the 1920s. Four factors are responsible: a record drop in coal use, the rapid growth of renewable energy, the expansion of energy efficiency programs, and the increased use of natural gas for electricity power plants.
2016 Carbon Progress Report
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.
Clean Coal For Real
We have heard the term “clean coal” for years, mostly from politicians and in coal company advertising. The concept sounds good: burn coal but don’t produce carbon dioxide emissions. While there have been various small-scale tests of technologies to accomplish this, it has not actually been a viable option for the power industry.
Turning Carbon Dioxide Into Rock
There is a lot of interest in figuring out a way to store carbon dioxide produced from industrial processes and energy plants or even sucking it out of the atmosphere and then storing it. The problem is where exactly to put the stuff and how to make sure that it stays there.
Using Less Energy
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
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.
The Carbon XPrize
The Carbon XPrize is a five-year, $20 million competition to identify ways to convert carbon emissions into successful, profitable and useful products. Forty-seven organizations from seven countries are competing for the prizes and include large companies, startups and university researchers.
Less Sulfur In The Soil
Acid rain is rain containing high levels of nitric and sulfuric acids. The main culprit for it is the burning of fossil fuels, particularly coal-burning power plants. The most serious effect of acid rain is the creation of toxicity in lakes, wetlands and other aquatic environments, doing great harm to a wide range of aquatic animals.
Clean Fossil Fuel Electricity
Renewable energy sources like wind and solar power are getting cheaper all the time and are, in many places, competing head to head on price with traditional fossil fuel generation. The ultimate goal is to replace polluting energy sources entirely, but even under the most optimistic scenarios, fossil fuel plants aren’t just going to disappear very quickly.
Carbon Counters
The Paris climate agreement last December resulted in commitments by 195 countries to reduce their carbon emissions. The countries around the world made specific pledges to reduce emissions in the form of “intended nationally determined contributions” or INDCs.
Pulling Water From Air
As droughts have become more commonplace, researchers are looking at natural systems for effective ways to capture water from the air. A team from Harvard University has drawn inspiration from three different organisms to develop a better way to promote the condensation and transportation of water droplets.
Carbon Capture Update
The global community is increasingly making commitments to reduce the amount of carbon emissions in the atmosphere. More and more carbon-free renewable energy sources are being used all the time. But despite the tremendous growth in solar and wind power, fossil fuels still provide about 80% of the world’s energy. Coal still provides about 40% of worldwide electricity. Realistically, these numbers can only go down at a relatively gradual pace.
Killer Air
Globally, air pollution kills 3.3 million people per year. And this number could double to 6.6 million people by 2050 if little is done to decrease the dangerous levels of tiny particles, toxins, and ozone in the air.
