Establishing a New England market to buy renewable energy seemed a laudable goal when governors committed last year to bulk purchases of wind and solar power to cut the price of alternative energy while reducing the regions reliance on fossil fuels. But putting together details about what the six states will buy is snared in a patchwork of rules, state laws and disagreements among the states over how to even define alternative energy.

There is good news about renewable energy, and it matters to all electricity consumers -- which means all of us.

So why am I qualified to share these facts with you?

In addition to being a former senior policy official at the Department of Energy and Deputy Manager of Power at the Tennessee Valley Authority, I spent the better part of three decades flying 4 million miles on United as I developed a startup global electric power and distribution company into a company with $18 billion a year in annual revenue and power plants now in 21 countries.

So here are six FACTS about the impending renewable energy revolution:

1. Most of what is called "renewable energy" is hydro, geothermal, wind and solar, with the last two being by far the largest. Big wind and solar plants are now cheaper to build than coal or nuclear plants -- the mainstays of utility generation. This is a major change from only a few years ago. In 2008, solar panels cost $3500 per Kw, with installation costs adding another $3500, for a total of about $7000 per Kw. Coal plants cost half that, nuclear projections were about $5000 per kw. Today's solar and wind plants can be built for about $1600 per Kw, and the nation's largest manufacturer of thin film panels, FirstSolar, projects reaching a cost level of less than $1000 by 2017.

2. Renewable energy is NOT going to provide lots of jobs. There are some construction jobs, but many are low skilled. After it's built, all you need is a few technicians monitoring the plant's output. You don't need the large group of plant operators and maintenance people, three shifts a day, all day, year-round, that a fossil or nuclear plant needs.

3. Traditional power plants take forever to site and build. They have big footprints, they are difficult to put near customers, and they generally require extensive local, state and national permitting. Solar can fit in just about anywhere -- all you need is roof space or a reasonable piece of more or less flat and unshaded ground. These installations can be put into densely populated areas just fine. The Europeans have limited space, but have put wind and solar in small installations in many places, some of them ingenious, including rooftop solar for car parks and wind machines on waste dumps. Solar panels are fast and easy to install. Once the frame is set up, all that's needed is to put the panel down, tighten four screws, and make a simple plug-in electrical connection. That's far easier than replacing the water heater in your home.

4. These things last. Solar panels really don't break -- they are just thin layers of silicon organized within an aluminum frame. If you take a sledge hammer to one or blast it with a shot gun, you will do some damage, but otherwise they just sit there and make electricity. Panels at test sites like the Argonne National Lab have been sitting outside and functioning for more than thirty years. The electrical conversion hardware, something called an inverter, may need occasional servicing, but it is simple and easy to replace. On rare occasions wind turbines lose a blade (two or three instances over the last twenty years) and wind turbine gear boxes and generators need routine lubrication and servicing, but they too have lasted longer than anticipated.

5. Renewables aren't just for the desert southwest or windy mountain passes any more. Major solar installations have gone in on Long Island and North Carolina; wind is a mainstay in the Pacific Northwest, and very large installations are underway in the plains states. Germany now gets 5 percent of its generating capacity from solar and 7.5 percent from wind --and that country is not at all a particularly windy or sunny place. Remember all those Germans going to the Mediterranean during the summer! Little wonder that last year in the US, renewables were the largest source of new electric generation to come on line at 32 percent of new generating capacity in 2014 and that this was a 30 percent increase over 2013. The International Energy Agency, a conservative forecaster in the best of times, now projects that by 2050 solar power will rise to 27 percent of all electric generation, worldwide, and thus become the biggest single source of power.

6. You will hear that intermittency is a problem for wind and solar, since the sun doesn't shine at night and the wind doesn't always blow. But (surprise) it's a problem for traditional plants, too. Big gas fired plants only have availability on average of 80 plus percent, and nuclear plants have to be shut down for three months or more for refueling every 18 to 24 months. For renewables, the problem is being rapidly solved by storage. Battery technologies are becoming cheaper and more efficient. Tesla has announced that it will make batteries for residential use which Solar City, the country's biggest residential solar company, has begun to offer to its homeowner customers and to commercial scale micro-grids.

So, isn't most of this good news? Wouldn't we all want safer, more cost-effective renewable energy alternatives?

Proponents recognize that this is the first-time ever that the end-user is able to make their own power in an effectively and efficient manner.

Detractors (the utility companies) would argue that if enough people choose to use renewable energy they will not be able to afford to provide the rest of us with service.

So is this a real Catch 22, or is there a way for the utility companies and renewable energy companies to work together?
