The truth about Solar in Minnesota

I recently returned from Greenbuild in Phoenix, where the Habitat for Humanity of Central Arizona built a LEED-Platinum Zero Energy Home! The Legacy Project, constructed in 5 days, was built for around $120,000 (including building materials and donated goods and labor), and used solar panels to offset the energy use in the home. After having a conversation with a good building contractor friend who is trying to be more green, I decided to investigate the truth about solar in Minnesota.

Does Minnesota have enough sun? Phoenix has 350 days a year of sunshine and definitely should be taking advantage of solar energy production. Minnesota actually has a lot of solar potential as well. According to the Minnesota Department of Commerce, Minnesota has more annual solar potential than Houston, Texas. They are a great resource for information on solar feasibility in Minnesota and even have a map that demonstrates solar potential. After looking at this site, you will see that while you may never create excess energy to go back into the grid, the potential for solar is definitely there. Combine this with a well-sealed house and energy-efficient appliances and living behaviors (e.g. turning off your computer when not in use), and you may be completely set!

Aren't solar panels still just too expensive? There are actually a lot of funding sources out there right now. The Database of State Incentives for Renewables & Efficiency can help you find funding for your renewable energy project. Like all things, they do cost money, but as energy prices increase over the next few years, the solar panels may be paying for themselves.

So what about local options? Can you get solar panels that both travel short distances and support our local economy? Minnesota offers two solar panel production plants:

SolarSkies in Starbuck, MN
tenKsolar in Bloomington, MN

What if I just don't like the look of solar panels or am not sold on solar?

Don't forget that the sun can help in ways other than just energy production - passive solar heating (orienting a house with south-facing windows that heat a large thermal mass) and solar hot water systems work great in Minnesota!

Other renewable energy options are also available. The Clean Energy Resource Team (CERTS) network and the Minnesota Renewable Energy Society can help point you in the right direction.

Greenbuild and Greening the Economy

I just returned from Boston for Greenbuild, the nation's largest green building conference. While I was somewhat disappointed at the lack of affordable methods to build green and information for rural communities, I came away very inspired and hopeful that America may finally be moving in the right direction, and that sustainability for all might one day be possible.

One of the master speakers was Van Jones, author of The Green Collar Economy. He gave an inspirational speech on how green jobs will both fix our economy and positively impact climate change. He also stressed the importance of our new president - not as the first black president, but as the first green president who is dedicated to improving sustainability, and how that is something everyone in the country will benefit from.

We should never lose sight of why we are doing what we're doing - Van Jones

In order to make green jobs successful, a complete shift toward sustainable thinking is needed. The only true way to get us out of this economic slump will be to invest in sustainability and green jobs, and basically do the opposite of the current model of our failed economy. Jones spoke of three shifts we need to make:

-Local Production. We're the largest consumers in the world, not producers. We currently consume 5-7% more than we produce, something that in Nature simply could never sustain itself.Shifting production of goods locally will not only produce more green jobs in our country, it also poses an opportunity to bring social benefits to everyone. And of course using local materials minimizes negative environmental impacts as well.

-Thrift. Our economy is powered by debt instead of smart savings, by credit instead of creativity, by borrowing instead of building. In Nature, nothing is free and no animal can survive a winter without harvesting and rationing energy wisely. In addition to saving money and being smarter about monetary choices, we should be more thrifty in our consumption as well. Think smaller homes, smaller cars, and more energy-efficient everything, and nothing bought on credit. Reward those that are doing a good job, not those that are failing.

-Environmental Restoration. Our economy runs on environmental devastation instead of protection and restoration. This model is simply not sustainable as there is no such thing as an endless supply of anything in Nature. Every choice we make needs to have an environmental focus. Choose materials and methods of energy that are renewable and durable, and practices that give back to the environment instead of taking away.

It seems so logical, doesn't it?

So where do we start? Looking at green building standards and finding good information at places like Dovetail's Eco-Affordable Housing Program is one good place to begin. According to Greenbuild master speaker Kevin O'Connor from television series This Old House, America currently has over 125 million homes that were built before today. So while looking at new construction is important, we need to be retrofitting America first to really change how our buildings are impacting the environment. It's also a great place to build some green jobs. Minnesota currently has its own green remodeling standards - among the very first in the country.

We need to retro-fit America - Van Jones

I found his speech very inspirational and believe that this economic downturn, while difficult, will prove to be the very thing we need to become more sustainable as a whole. It's really exciting, if only we can remember that now we're free to fly or fall - and we have the choice of which way to go. We can no longer ignore sustainability - it is going to be the thing to make us succeed instead of being something to be afraid of.

One thing to note is that as green building shifts even further to the mainstream and more green jobs become available, those of us that have been doing green for a long will no longer be the alternative, we will be the cornerstone of the industry and the economy. It is important that we are informed by good information and that we continue to help others who ask for it, even though we are essentially competing for a piece of the green pie. This shift is already becoming apparent at Greenbuild, where vendors were much more informed of environmental jargon than last year, and which was attended by more green building consultants than ever. Let's continue to help each other by both being open with our environmental information and also choosing sustainability for the wellness of our society as a whole.
