The Copycat Syndrome, Innovation and Not Giving Up

Call it the copycat syndrome or marketing burnout wherein a company has a success with one product at which point every company in the space copies the effort leaving a market dotted with me-too products with little differentiation other than price. Eventually through this process value is suctioned out of the product or service, demand wanes, and consumers move on. It is almost impossible to satisfy consumer desire for the cheapest or most innovative product/technology/service/oh-heck-anything, particularly because in the end the equilibrium price may well be zero and innovation may be defined as simply announcing that something is innovative.

Rising Energy Dependency Endangers Europe’s Economy

The issue of energy may have been overshadowed by that of tax at yesterday’s EU summit of Heads of State in Brussels, but its growing importance and impact on Europe’s economy is one that cannot be ignored. As the Financial Times reported on Tuesday, Europeans are paying a lot for their energy – prices are 37% higher than those in the US and 20% hi

How to Generate Better Intelligence, More Wind Power and Increased Profits

Since 2007, more than 40,000 MW of new wind generation has been built in the U.S., according to the American Wind Energy Association (AWEA). Tens of thousands of new turbines are operating, a testament to the entrepreneurial and engineering spirit of renewable development firms, equipment suppliers and engineering, procurement and construction (EPC) companies.

Solar Tax Credit Creates Opportunity for Indian Tribes

Many American Indian tribes have been considering business opportunities in connection with solar projects. To date, most of the focus has been with respect to the siting of utility scale solar projects on tribal land in the desert. For instance, the Moapa Band of Paiute Indians have leased land on their Nevada reservation for a 250 MW solar project being developed by kRoad Solar.

GM’s Commitment to Solar Going Strong

With the amount of energy required to produce a vehicle, it makes sense that automobile manufacturers are exploring solar power to help cut costs and position themselves as environmentally-conscious companies. Incorporating solar energy into their operations is already popular among European vehicle manufacturers: from SEAT’s 10.6 megawatts (MW) of

UK Urged to Boost Clean Energy Over Natural Gas

Britain, under pressure to build new power stations, could save as much as 100 billion pounds ($150 billion) through 2050 by spending on wind, nuclear and carbon capture rather than gas, the government’s climate adviser said.

Lead-Acid Batteries: Merely A Launch Pad for Something Better?

There’s finally been some good news for a change: According to a recent analysis performed by market research company IHS, the market for photovoltaic storage systems is about to boom. In Germany alone, the total capacity is set to increase from eight to 4,900 megawatts (MW) between now and 2017. The success of storage systems is dependent on one condition, however: They must be able to pay for themselves within the estimated 20-year lifetime of a solar plant, as well as operate reliably in basements throughout the year.

Rumors of US-China Trade Settlement Talks Fuel Solar Stocks

If short-term traders really have hijacked the sector, which seems probable, it would mark a relatively big setback for stocks that were once popular among aggressive longer-term investors who liked the strong prospects of solar energy. Of course that doesn’t mean that serious investors will never return to the sector if it ever manages to stabiliz

Despite Fears, New Renewables Are Not Bankrupting California

Until recently, the potential rate impact of all the new contracts for renewable energy being added to meet California’s Renewable Portfolio Standard since 2006 has been a matter of some concern. According to the Division of Ratepayer Advocates in early 2012, an estimated $20.8 billion will have been spent in California on contracts for new renewable generation by 2020, and the rate impact was a big unknown.
