EU Looking to Get Tough on Companies Over Energy AuditsIt is no secret that companies contribute on a massive scale to overall carbon emissions through their operations whether local, national or global. But the question for a long time has been what to do about it and how to encourage enterprises towards practices that help reduce the scale of their carbon footprints.

Well, within the European Union (EU) at least, one important policy in this context relates to energy audits, through which companies can gain a better and more accurate sense of how they use or misuse non-renewable energy resources. The hope and expectation is that by investing in these so-called ‘green’ audits, businesses will become more willing and able to reduce their energy use and save money in the long term. (more…)

More on Setback to the U.S. Environmental Protection AgencyIn my recent post called “Setback to the U.S. Environmental Protection Agency” I noted:

Environmentalists everywhere were saddened that the U.S. Supreme Court dealt a blow to the Environmental Protection Agency with its recent ruling invalidating the EPA’s regulation of mercury and other toxic chemicals that are emitted from power plants.  But at the same time, as much as I hate to say it, the ruling is a validation of common sense…..The EPA’s position was that it could do its thing without regard to the costs incurred by the power plants.  Really?  How smart was that?  (more…)

Profile of a World-Changer: George SandMost of us suffer under the delusion that we, as individuals, are powerless to make much difference on a planet that’s home to more than seven billion people—not to mention some enormous corporate interests that are intent on preserving our current murderous practices vis-à-vis our environment.   That’s why it’s a good idea to celebrate the lives of people who, fortunately for us all, simply didn’t fall into that psychological trap.

It’s the birthday of French author George Sand (pictured with Frederic Chopin), thus a good opportunity to consider how single individuals can change the course of history.  According to the Writer’s Almanac: (more…)

electric vehicles charged with renewable energyNot being a “car guy,” I’m unimpressed with concept cars that show the future of automotive design—especially as they suggest perpetuating of the basic paradigm that has been with us for 100 years: big, sleek, expensive compartments that run on gasoline and shuttle us and our belongings around.

Automakers are in the process of realizing, much to their horror, that the world is making sweeping changes to the overall line of thinking in transportation (which is why Uber is currently valued at $50 billion). (more…)

Admittedly Off-Topic: The Word of the DayI enjoy the discussions that I routinely have with my mother on “the word of the day” on dictionary.com.  Here’s what I wrote to her re: today’s word: “contradistinction,” meaning “distinction by opposition or contrast”:

The reason I don’t use “contradistinction” is that I regard it as redundant.  “Distinction” already implies the concept of “contrasted against.” 

I have a friend who uses the word “prewarn,” apparently unaware that “warn” means to give advanced notice of danger; one doesn’t warn someone of something that has already happened. Of course, there are people who admonish “be careful!” when someone has bumped his head, but that’s really idiotic.

What You Can Do With a Rotary Dryer?Fossil fuel resource is limited in this world. Coal, oil, gas will someday go to the end of its destiny. Government and institutes are advocate substitute fuel. Biomass energy is emerging and growing rapidly in recent years, not only because they are sustainable, but also less pollution.

Many agricultural and forest residues could be used for biomass briquettes production, rather than simply burning. Many materials, like sawdust, wood chips, barks, stalk, bagasse, vinasse, husk and hull, are dried and briquetted/pelleted. (more…)

Unique Approach To Hydrokinetics: Harvesting the Energy of RainI have to give this guy credit for thinking outside the box.  Here’s his patent for converting the mechanical energy from falling raindrops into electricity.

Will it work?  Sure.  Does it represent a potentially cost-effective solution in the renewable energy space?  Not in a million years, but that’s no reason to stop creating new ideas in this arena.

How to Save Energy on Summer NightsWhenever summer does arrive, everyone seems to do there best to make the most of it. However fleeting the nice weather might be, most people waste no time in wheeling out the BBQ’s and the sun loungers.

But just because it’s time for some recreational activities outside, it doesn’t mean you have to stop being environment conscious. Opportunities to be eco-friendly are abundant in today’s society, and that includes during the summer. (more…)

Benefits of Briquetting Technology Briquetting is a process that agglomerate powders and fines together to produce solid briquettes under high pressure, and most of the time, with the help of binder and high pressure.

Initially, coal briquettes are made during WWII for home heating in cold winter. To this day, coal briquetting is still an effective way to recycle coal fines and upgrade LRC (low rank coal). This technique is widely used in countries that are rich in coal resources, like India, Australia, Indonesia, South Africa, China, etc. (more…)
