One still hears reference to “the debate on global warming”. Is there really a debate? Certainly, there are people who want to think there is, especially those with a vested interest in not doing anything about it.
Several major automakers including Toyota, Honda and BMW are betting that hydrogen-fueled cars will be a dominant technology in the future. There are a number of technical and economic problems to be solved before that can happen. Producing hydrogen in an cost-effective and environmentally-friendly way is critical. But beyond that, one of the biggest challenges is the transportation and storage of hydrogen.
The seafood industry is one of the largest employers in the world. But according to a 2016 report, the seafood industry also contains widespread forced labor. Forty seven seafood-producing countries were reported to utilize forced labor. The seafood hub countries of Indonesia, Thailand, Vietnam, Peru, and the Philippines were also reported to use a significant percentage of child labor.
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 recent study published in Nature Climate Change looked at what emission reductions are needed to meet the climate targets of the Paris Accords. The results are sobering.
One way or another, the fossil fuel industry seems to be destined to shrink away. A combination of technological advances and climate policies are going to drastically reduce the global demand for fossil fuels over the course of time. New research shows that the demise of the fossil fuel industry will have profound consequences.
Tourism is a significant contributor to global gross domestic product. Furthermore, it is growing at an annual rate of 4%, more than many other economic sectors. There are many places around the world where it is the largest industry. But until recently, there really wasn’t very good information about its carbon footprint.
U.S. automakers have always been reluctant partners in the nation’s efforts to reduce air pollution and improve fuel efficiency. There have been struggles for decades between the carmakers and the government in setting Corporate Average Fuel Economy (or CAFÉ) standards. During the Obama administration, some of the most demanding fuel economy and emissions standards were mandated.
According to a new report by the International Renewable Energy Agency, more than half a million new jobs were generated by the renewable energy industry last year, an increase of 5.3% when compared with 2016. The total number of people working in the renewables sector – which includes large hydropower facilities – has now exceeded 10 million people worldwide.
Diesel cars have never been very popular in the US and in the aftermath of the so-called Dieselgate scandal at Volkswagen, they are even less so. Less than a dozen diesel car models are available for purchase in the US and only one of those is from a German automaker: BMW.
The United States has now added the capacity to store a billion watts of power for one hour and it may double that total by the end of this year. According to the firm GTM Research, the energy storage industry – previously nearly invisible – is undergoing rapid growth. Much of the growth has been in homes with products like the Tesla Powerwall but has also been on the scale of the electric grid, where power companies can use storage to control when to deploy excess electricity generated from renewable sources such as solar power.
Firebricks, which are bricks designed to withstand high heat, have been around for more than 3000 years. The Hittites used them to line iron-smelting kilns. They are simply bricks made from clays that can withstand much higher temperatures than ordinary bricks.
A byproduct of plastics production, dioxane is a clear, synthetic, liquid solvent that easily mixes with water. It’s frequently used in paint strippers, dyes, and varnishes, as well as shampoos and body washes – particularly those that are sudsy. Dioxane doesn’t really biodegrade and is widely regarded as a contaminant.
In a recent report to a United Nations ocean conference, scientists are warning that new rules are desperately needed to protect marine life in the open seas. That’s because more than 60% of the ocean has no conservation rules since it’s located outside national jurisdictions. The open ocean is at risk from climate change, over-fishing, deep sea mining, farm pollution, and plastics pollution.
We have talked about the problem of food waste before. About 40% of the food produced in the United States goes to waste, which is a truly shameful statistic. According to a Business for Social Responsibility study on the subject, about 44% of the food that goes into landfills comes from homes. About a third comes from the food service industry.
According to the Roundtable on Sustainable Palm Oil or RSPO, almost 12 million tons, or 21% of the global supply of palm oil, is now certified as responsible and sustainable. The massive expansion of palm oil plantations has been one of the primary causes of global deforestation. This has been especially the case in Borneo, where 85% of global palm oil production takes place.
Poor air quality is a problem all around the world. Exposure to air pollution is linked to the premature deaths of an estimated 6.5 million people every year, making it the fourth largest threat to human health, trailing only high blood pressure, dietary risks, and smoking.
There is a tendency to think of the changes in the energy industry as a pitched battle between fossil fuel companies and renewable energy. There is some truth to this, but only to a certain extent. The multi-trillion-dollar fossil fuel industry is made up of businesses dedicated to growth and increased profits. And like businesses in other industries when major changes occur, fossil fuel companies may read the tea leaves and change with the times.
Poor air quality is a major problem worldwide. Exposure to air pollution is linked to the premature deaths of an estimated 6.5 million people every year. This makes air pollution the fourth largest threat to human health, trailing only high blood pressure, dietary risks, and smoking.
Despite efforts by the new administration to increase support for fossil fuels, there is increasing momentum towards a clean-energy future. State and local efforts are driving the country to a 21st-century energy infrastructure, with or without the federal government.
