Europe’s E-Mobility
With the arrival of the Chevy Bolt and the long waiting list for the forthcoming Tesla 3, there is starting to be some momentum for electric cars in the United States. But we are still well behind Europe in terms of the significant growth of so-called e-mobility.
The Success Of SunShot
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.
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.
European Lessons On Food Waste
Americans toss out an almost unbelievable $161 billion worth of food every year. There are numerous efforts underway to address this problem, but they are mostly at the local level or in the business sector. To date, we have no national- or international-level policies that tackle the issue. In this regard, Europe is way ahead of us.
Last Year Was Hot
Last year was not the hottest year on record in the United States; it was only the second hottest. 2012 was the hottest because of some searing heat waves that summer. However, 2016 marked 20 above-average temperature years in a row. The five hottest years recorded have all happened since 1998. Every state had a temperature ranking at least in the top seven and both Georgia and Alaska had their hottest years ever. While it was only the second hottest year on record in the U.S., last year was the hottest year for the entire world.
Northeast Temperatures
A year ago, nearly 200 countries signed an agreement, known as the Paris Accord, to fight climate change by mitigating greenhouse gas emissions. They each promised to reduce their carbon output as soon as possible, and to do their best to keep global warming well below 2-degrees Celsius (or 3.6 degrees Fahrenheit).
Energy From Jellyfish
Jellyfish are fascinating in appearance but generally are nothing but trouble. Their stings can ruin a tropical vacation but they can cause far more damage than that.
Clean Power Is Cheap Power
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.
Climate Engineering
With the forthcoming administration change, it appears that the federal government is likely to start backing away from tackling climate change and may even be obstructive towards efforts to mitigate the growing problem of greenhouse gas emissions.
Giant Wind Turbines
Wind turbines have been getting bigger and bigger over the years. The reason is that bigger blades produce more power and give much more bang for the buck. A big part of the plummeting price of wind power is the increasing amount of power produced by each turbine.
China As Climate Leader
China and the United States today produce nearly half of the world’s carbon emissions, so the fight against global climate change depends greatly upon what actions the two countries take. China has undergone a dramatic transformation over the past twenty years from a largely rural society to one that is far more urbanized and far more energy intensive. In 1997, when the Kyoto Protocol on climate was negotiated, China was only responsible for 14% of global CO2 emissions. It then surpassed the US on that front in less than 10 years and now accounts for nearly 30% of the world’s emissions.
Extreme Cold And Climate Change
Global climate change is typically referred to as global warming and that name implies that things are getting warmer all the time. Well, the planet as a whole is, as measured by the planet-wide mean temperature, which continues to rise over time.
