It was 1985 when the first Tour de Sol, a Swiss rally for solar powered vehicles, ushered in a new era of design and innovation for solar energy use. Among the first of its kind, the contest challenged teams of students and engineers to use solar cells to propel their “racecars” through Swiss towns. Now, nearly 30 years later, similar competitions all over the world openly invite interested parties to engage with solar technology in ways that maintain the velocity of its innovation and implementation.

Microgrids, They’re Kind of a Big Deal

MicrogridFor locals participating in the Pecan Street Demonstration in Austin’s suburban town of Mueller, TX, residential carbon footprint data is about as available as square footage. Their home utility consumption is monitored by the Pecan Street Research Institute at The University of Texas-Austin as part of the institute’s efforts to understand how individuals can lower their collective carbon impact and use energy more efficiently. This new technology, known as a smart grid system, has proven to be much more efficient than the traditional electrical grid used throughout the US. However, smart grids and the smart meters used to track energy usage of individual homes have come under fire for their ‘invasiveness’ as people have vocalized concerns about the lack of privacy that could accompany this advanced monitoring system. Fortunately for the anti-smart meter crowd, there are other ways to make a community more energy efficient.

How the solar energy industry is becoming one of the most widely beneficial sectors in the country

New York Solar

Things are looking up for the solar energy industry. Its growth has skyrocketed over the past few years and is projected to endure. If current trends continue, solar will account for 10% of American electricity by 2022.
A diverse array of stakeholders is largely affected by this booming industry, from veterans to homeowners to that all-pervading stakeholder, the environment. To help understand the state of the industry and what’s on the horizon, here’s a list of the ways in which the solar energy industry is fast becoming one of the most valuable sectors in the nation.

2012 ends as a year of uncertainty. Uncertainty about the political landscape, uncertainty about climate change, and uncertainty about business have weighed heavily on our clients minds. At least the Mayan calendar did not end. What is certain is that 2013 looks to be a good year.

Energy plays a significant role as we look ahead to 2013. It fuels and impedes business success. It causes global climate change yet holds many of the solutions to this crisis. The politics of energy reflect the transformation that is happening throughout our economy. Old ways are dying and old industries and business practices are becoming relics relegated to the LA Brea Tar Pits of time. The more entrenched businesses and industries become, the more they sink into the past. Innovation, technology, and new economic models are creating the next generation of great businesses, and their approach to energy is critical to their success.

We look at 2013 as a year for performance and it reflects our optimism for all the business opportunity we see across the country. We sense this in conversations with our clients and our colleagues. Businesses are looking ahead and planning for long term growth and success. 2013 looks like it will be the year of the long play, where smart investments position businesses for future success. Here are a few trends to take advantage of in 2013.

Roadmap for Solar Energy Development in Six Southwestern States

Tuesday, October 9, 2012 10:11
Posted in category Uncategorized

WASHINGTON – As part of President Obama’s all-of-the-above energy strategy, the Department of the Interior, in partnership with the Department of Energy, will publish the Final Programmatic Environmental Impact Statement (PEIS) for solar energy development in six southwestern states—Arizona, California, Colorado, Nevada, New Mexico, and Utah. The final Solar PEIS represents a major step forward in the permitting of utility-scale solar energy on public lands throughout the west.

Today’s announcement builds on the historic progress made in fostering renewable energy development on public lands. When President Obama took office, there were no solar projects permitted on public lands; since 2009, Interior has approved 17 utility-scale solar energy projects that, when built, will produce nearly 5,900 megawatts of energy—enough to power approximately 1.8 million American homes. Thanks to steps already taken by this administration, renewable energy from sources like wind and solar have doubled since the President took office.

The fastest growing energy technology industry in the world, grid-connected solar photovolatics (PV), is growing nearly 50 percent in capacity each year, as costs fall, more workers are trained in solar installation and more consumers become educated about the new technology. According to a 2011 study by PVinsights’ market intelligence report, here are the Top 10 solar PV brands:

Solar Energy

Best Solar PV Brands:

  1. Suntech (offices in 13 countries)
  2. First Solar

Can the World Rely Solely on Renewable Energy?

Wednesday, October 3, 2012 10:40
Posted in category Solar Installer Articles

Wind EnergyThe answer certainly isn’t a simple “yes” or “no.” There are many factors to take into account when one is considering how realistic it would be for the world to rely solely on renewable energy. One of the main considerations is intermittency. Though solar are wind energy are excellent substitutions for fossil fuels, the sun isn’t always shining and the wind isn’t always blowing.

Because the average world citizen gets 90 percent of his/her energy from traditional fossil fuels and about 10 percent from renewable sources, the transition to full renewable generation is a daunting task. Of course, it’s become very clear that fossil fuels are not sustainable for many reasons, predominately because of the climate-altering effects of carbon emissions. In addition, as fossil fuels become more scarce, the methods used to extract them become more intensive and environmentally devastating, so it’s important to find ways to source our energy in a way that works for the long-term.

The truth is, energy investments and build-outs are measured in decades, not years and efficiency is the most effective “clean energy source” available to us today. You might have noticed a good bit of change in the automotive industry lately, with more hybrids and electric vehicles being put on the market. The auto industry is one of the leading examples of a race towards more efficient technologies leading to a decrease in emissions.

So, how can we expand the idea of putting more renewable energy resources in place beyond simply using dirty sources more efficiently, and is it even worth it?
