  • Something To Consider Before Buying In To Rooftop Solar

    Green energy has moved to the forefront of the national conversation on energy production even as oil prices sit near decade lows. The simple fact that solar power and wind power now command so much attention speaks to how the country’s views on energy have changed. But now some people are going one step further and actually looking to install enough solar panels on their homes to become energy positive – that is to generate more energy than they actually consume. Britain’s Guardian newspaper ran a recent story about this , but that story skipped over a few obvious issues.…

  • How Much Money Can You Really Save With A Smart Home?

    It has become conventional wisdom that the wave of the future is “smart home” technology from smart utility meters that read a houses energy usage automatically to smart lights that turn off when not in use. The industry has been in development for years, but moved to the forefront of the start-up world when Google bought Nest Labs last year for more than $3B. Nest Labs makes a variety of smart home devices including thermostats and smoke alarms. Smart home technology marries two of the most talked about trends in business right now – the internet of things and green…

  • Off-Grid Solar Threatens Utilites In The Next Decade

    The utility death spiral could be just around the corner. A new report from the Rocky Mountain Institute (RMI) finds that solar photovoltaics combined with battery storage could become cost competitive with grid electricity in key parts of the United States within a decade. That would pose an existential threat to the traditional utility. As more homes and businesses opt for solar power equipped with battery backup storage, utilities will lose their customers. That makes it increasingly difficult to finance and maintain expensive grid assets, forcing utilities to raise rates on remaining customers, further pushing people to go off-grid. For…

  • Time To Get Back Into Canadian Solar

    Longtime, regular readers with the memory of an elephant may remember an article that I wrote in May of last year. That piece suggested that even though solar power stocks had fairly consistently failed to live up to expectations, the ridiculously low valuations at the time made a couple of them worth buying. One of those suggestions was Canadian Solar (CSIQ).In that article, as is my wont, I also suggested parameters for the trade; a stop loss just below $20, which was never reached, and a price target of $37, which, as it happens, was actually about 10 percent away…

  • Solar Really Can Be Cheaper Than Coal

    The ongoing volatility in the oil markets has led many major companies to dramatically slash their capex budgets and workforces in a bid to survive. The knock on effect of this can be seen in a burgeoning solar industry that is seizing the opportunity to finally make a significant breakthrough into the market, regardless of subsidies. Research and consultancy group Woods Mackenzie believes we may have a shale-like boom on our hands. According to their new report “Is solar the next shale?” distributed and utility scale solar is nearly ready to transform power markets. And for this, we can thank…

  • The World's 10 Biggest Solar Farms

    Solar power may have its critics, with many pointing out the intermittency limitation compared to traditional energy stalwarts like coal, oil and gas. But there is no denying that the photovoltaic (PV) industry is on the move, with many developed nations – notably China, Japan, Germany and the United States – making huge investments into ground- and roof-mounted solar panels. A study by the Global Climate & Energy Project concluded that if current growth rates continue, by 2020 about 10 percent of the world's electricity could be produced by PV systems. A big part of the solar story is the…

  • This Solar Company Keeps Reporting Losses But You May Want To Buy It Anyway

    We all know that logically we should assess the value and prospects of any stock based on the profitability and prospects of the company. That is investing 101, but sometimes other factors take over. In the case of SolarCity Corp (SCTY), buyers seem to be motivated by anything but profitability. The company has never made a profit since the IPO nearly two years ago, but even so, despite losing a lot of ground since the high back in February, SCTY is trading at over five times what it was then. The gut reaction of any value investor when looking at…

  • How A Solar Revolution Could Be Near

    Credit: ShutterstockCan we build enough carbon-free energy fast enough to avert catastrophic climate change without having to power this energy transition with fossil fuels that would undermine the whole transition? The answer is “yes,” and here’s why.The “global solar photovoltaic industry is likely now a net energy producer,” concluded a Stanford study released last year. That was followed by a very detailed analysis, Energy Balance of the Global Photovoltaic (PV) Industry, by post-doc Michael Dale and Global Climate & Energy Project director Sally Benson. They examined how much energy is consumed during the entire lifecycle of the production process for…

  • Could Solar Provide 27% Of World’s Energy By 2050?

    Rapid Expansion of Solar Depends on Massive Subsidies and High Carbon PriceThe International Energy Agency updated their technology roadmaps for solar PV and solar thermal energy, suggesting that, with significant policy and technological progress, solar could collectively contribute 27 percent of global electricity by 2050. Some commentators were quick to exclaim victory, but let’s remember that the IEA has provided a “roadmap” not a set of predictions, nor projections. To achieve that 27 percent requires a high global carbon price – which doesn’t yet exist – and for average annual solar PV deployment to quadruple from 36 GW installed in…

  • India Is Committed To Solar, But Don’t Invest Just Yet

    In an interview this week with the Guardian newspaper, India’s power and coal minister, Piyush Goyal, claimed that India would become a “renewable superpower” in the next few years. Before we get too excited about the environmental impacts of that ambitious goal, however, it should be noted that Goyal also envisages a simultaneous huge ramp up in coal-powered electricity production. This illustrates once again that while India sees renewable energy, and solar in particular, as part of the country’s long term energy plan, the country’s priority is an urgent need to expand the electricity supply any way possible.For this and…
