I just returned from a ~7-mile hike I took by myself in preparation for next weekend’s far more strenuous Point Sal hike with a friend. Check out these images!

At the risk of appearing to be a weirdo, when I hike by myself I often contemplate the world’s situation at a macro level and what, if anything, I can do about it. This afternoon, I traversed a few of those miles thinking about the words of the eminent oceanographer Sylvia Earle, whose viewpoints I summarize as follows:

If you have a colony of bacteria in a petri dish, they multiply and eat, multiply and eat, multiply and eat, until they run out of food and room, and soon thereafter they’re all dead. They have no capacity for any other behavior; in particular, they have no sense that there could be consequences to unsustainable growth and runaway consumption of resources. People, on the other hand, most certainly have a sense of future, and recognize that there are consequences to right vs. wrong, to prudent vs. foolish actions.

But, I ask, given the outrageous rate at which we’re destroying our natural environment and chewing through our resources, will this capacity manifest itself in time to prevent us from the same fate as the bacteria?  There certainly are a few factors that provide cause for alarm: (more…)

Everyone knows that there is a limited supply of fossil fuel left on Earth and this may pose a big problem in the future. This issue is not only a major concern for the big corporations and businesses, but is also affecting the masses too. With the recent energy price hike, people are now looking for alternative energy sources to keep their bills to a minimum. Businesses are also looking for alternate sources of energy as a backup power source in case of blackouts. There are many alternative sources of energy and some have even taken the liberty of turning it into business, which is quite convenient for home owners.

There’s a bitter irony that strikes us all in our quest for total energy independence and a sustainable, clean energy future. Few will argue that natural gas is our ticket to the freedom of domestic energy production. It’s clean, cheaper than ever, and bountiful throughout the continental United States.

The natural gas that lingers between the Earth’s shallow soil layers are close to becoming depleted in the next decade or two. But about 10,000 feet down across the county lays the mother of all natural gas reserves – about 1,887 trillion cubic feet in total – which can be tapped with a process called hydraulic fracturing.

Ukraine is intended to become a new leader in solar energy production in Europe! Modern energy trends and statistics feature a rapid growth of solar power generation, which is associated with favorable natural conditions. According to experts’ opinion, Ukraine can boast of better irradiation facilities, than Germany – a current front-runner in solar energy production. In addition, effective energy policy of Ukrainian government has drawn an attention of numerous foreign investors, interested in distribution of solar cell panels. (more…)

I may have mentioned that, when it comes to travel, I’m almost always able to combine business with pleasure. This Monday morning I’m taking off with my wife and 16-year-old daughter to visit a few colleges between here (near Santa Barbara) and San Francisco. Simultaneously, I’ll be sneaking in a day at Intersolar 2012, an absolutely huge conference in which speakers and exhibitors with cutting-edge products and ideas, primarily in the photovoltaics space, come from all over the world.

I encourage anyone in the Bay Area who wishes to say hello to contact me and arrange a time and place to meet.

Here’s an article that falls into the category: “It would be funny if it weren’t so tragic.” Apparently, the heat wave is convincing Americans that climate change is real. They scoffed at the overwhelming consensus of the scientific community, and the hundreds of pictures they had seen showing how rapidly the glaciers are melting. But when they went outside and realized: man, it’s really hot out here, they got on board.

Whatever it takes, I suppose.

According to The Writer’s Almanac, today is the anniversary of the first official convention of the Republican Party, which was:

… held in Jackson, Michigan, on this date in 1854. Nearly 10,000 people turned out for a meeting in protest of the Kansas-Nebraska Act, which had provided for the expansion of slavery into the new western territories. …. The party’s name was formally adopted at this meeting, and was a reference to Thomas Jefferson’s Democratic-Republican Party. New York magazine magnate Horace Greeley wrote in an editorial: “We think some simple name like ‘Republican’ would more fitly designate those who had united to restore the Union to its true mission of champion […] of Liberty rather than propagandist of slavery.”

Good going, Republicans!

Now, 158 years later, I call upon you to exhibit the same compassion for all your fellow citizens, and support the cause of clean energy and environmentalism more generally. There is more at stake here than the destiny of the spotted owl and the desert tortoise. In fact, the entire fate of humankind on this planet depends on what we do here and now with respect to energy policy. Let’s get this one right.

It’s no secret that today’s car manufacturers have spent a good deal of time in the first decade of 2000 to present day on making their vehicles as fuel efficient as possible.  From aerodynamic changes to more streamlined mechanisms underneath the hood, whereas 25 MPG was a starting point, it’s looking more and more likely that most models will achieve 30+ MPG in the near future.

Many of us are scratching our heads, wondering how it’s possible that renewable energy, for all its merits, could be so slow to replace fossil fuels. As outlined in this article on Chesapeake Energy (our second largest natural gas producer), the answer lies in subsidies and other forms of preferential treatment. If you’re in a hurry, skip to the last paragraph, where you’ll learn how it’s possible that Chesapeake pays less than 1% income tax.

I just searched the 2GreenEnergy site for “level playing field for renewable energy” and realized that, over the years, I’ve written 34 posts that touch the subject.  If the good folks in Washington would simply remove the subsidies for fossil fuels and establish such a level playing field, we’ll have fantastic job growth, and all the other social benefits that accrue to clean energy, including the granddaddy of them all: a healthy planet.

Solar panels are starting to become an affordable way for consumers to contribute to stopping global warming. Unfortunately, only about one fifth of the population has enough usable space where solar panels can be installed.

Imagine how much the residential solar market would accelerate if solar power would be doable for everyone – even for those living in a huge apartment building in the city.

Net Metering

Typically, one of the ways people can afford solar is through the net metering program. (more…)
