Water scarcity affects 2.7 billion people worldwide for at least a month each year and in the same way that each of us has a carbon footprint, Professor Arjen Hoekstra of the University of Twente in the Netherlands posits that every person also has a “water footprint”. Our water footprint is calculated by counting the amount of fresh water that we each use daily and the amount of water required to produce the goods and services that we (more…)
Here’s an article on electric vehicles that suggests that three-quarters of new car shoppers are unaware that EVs even exist. I’m somewhat surprised by that, and I wonder if the questions weren’t worded improperly or the sample isn’t somehow skewed.
I’m reminded of my interview with Dr. Michael (more…)
Like a good financial portfolio, it appears that diversification is a successful strategy for America’s Energy Productivity according to the environmental action group, Natural Resources Defense Council (NRDC). But, the NRDC notes that while the energy portfolio clearly should include a combination of all energies, the single most effective tool in maximizing our energy (more…)
Today is World Environment Day, a date established in 1970 to raise awareness of pressing ecological issues. Every year, the United Nations Environmental Protection agency chooses a theme to promote on this date; in 2013 the theme is food waste. One third of the food produced globally is wasted and, with it, we waste a great deal of energy and water as well, since (more…)
Here’s a good discussion of what I call the “no free lunch” theory of renewable energy: everything we do, whether it’s solar, wind, hydrokinetics, etc., comes with a non-negligible ecological cost. The issue, obviously, is objectively identifying all costs – ecological, financial, and human (e.g., disease and death stemming from various types of energy generation and consumption), (more…)
The Green Power Hike, which recently took place in Hong Kong, is an annual fundraising event that focuses on environmental conservation and education. It’s a great initiative, but it serves as another reminder of just how inundated my daily life has become by the word “green” and how many different meanings the word has come to adopt. I am beginning to think that (more…)
In a recently released report, the Annual Energy Outlook 2013 (AEO2013), the US Energy Information Administration (EIA) projected the US energy markets through 2040. Their projections only take into account the effects of policies that have already been implemented in law or final regulations. The EIA found that the growth in energy production has (more…)
Coal could rival oil as the world’s largest energy source within five years as consumption continues to climb in most regions of the world, a trend that could have profound effects on the climate, the International Energy Agency (IEA) says.
While coal consumption is expected to decline in the (more…)
Every now and then, an exciting opportunity to experience the world comes by and you just have to say what the heck and toss your hat in the ring. If you are interested in sustainability and in particular the so-called water energy nexus, the opportunity of a lifetime is here.
