Peak oil? coal? gas? tar sands? shale gas? or any such? New discoveries seem to outpace all fears of early shortages. CO2 and AGW worries groundless? The jury is still out on that. Does that mean we can live free of any worries and carry on without any further need for doomsayers and troglodytes? Well yes, based on such questions. But could it just be possible that these are not the right questions to ask as they might produce wrong answers and consequently lead to wrong policies and investments?
Standards-based solutions were instrumental in the exponential growth of the Internet. For the Smart City, public electrical infrastructure ecosystem to expand, development, application and worker training of interoperability standards is an important strategic foundation from which to grow. This convergence of intelligent transportation systems with the Smart Grid, is allowing the Smart City concept to gain hold in many areas of the US and around the world.
Undermining the Pentagon's alternative energy plans can only be political, and specifically a Republican attempt to undermine the largely energy-focused campaign of President Barack Obama. After the elections, it should regain lost traction the next time it comes around for a vote.
Lincoln International's Renewable Energy Group is pleased to present the latest Q1 2012 Solar Energy Stock Index Report, which tracks relevant solar company metrics in this growing industry.
With the elimination of federal incentives for renewable generation, more than $20 billion may be shifted from the federal level (i.e. all taxpayers) to the customers in states with RPS targets.
Grid parity happens when large scale solar can compete with, or beat wholesale pricing from coal plants, the nuclear facilities and combined cycle natural gas.
Region set for more than 60% growth in 2012; Downstream companies will need to adapt to changes in end-market
When the dust settled, 353 transactions had been completed for a reported $13.9 billion—down 6% from the $14.7 billion posted in 2010. While greentech funding rose 4% to $10.6 billion, mergers and acquisitions slumped 29% to $3.3 billion.
The global cumulative installed capacity for solar PV is expected to reach 330,424 MW by 2020, growing at a CAGR of 23.7% during 2011-2020. Europe is the leading solar PV market, with a share of 76.5% of the total cumulative installed capacity, followed by the Asia-Pacific region, accounting for a share of 15.8% in 2010.
The Kyoto Protocol, having set binding targets for 37( + 4 that are to be added till the end of 2012) developed countries to reduce GHG emissions to 10-20 percent below the 1990 levels by 2012, however, may lose its significance in the second period since some countries such as Canada, Japan and China were reportedly unwilling to take part.
MIT report shows that with new policies, U.S. electric grid could handle expected influx of electric cars and wind and solar generation.
Unirac is a strong advocate for developing new codes for solar infrastructure, and has been working closely with the International Code Council Evaluation Service to develop new performance standards for racking and mounting systems. Unirac's new SolarMount (E)volution residential roof mount PV racking system, launched at Solar Power International in October, is currently being evaluated by ICC-ES. Unirac is the first company to apply for an ICC ESR under ICC-ES AC428.
The program's goals are nothing if not ambitious, as the government had initially hoped to boost the nation's solar capacity by the equivalent of about 18 nuclear power plants by 2022, a date that's now been brought forward by five years.
A grid-interactive PV system implies that a PV system is tied to the grid but can stand alone if the grid goes down. Essentially, it offers the best of both off-grid and grid-tied systems.
Caught between strong utility-scale project demand, declining solar incentives in distributed generation applications, module over-supply, and significant policy uncertainty, the North American photovoltaic (PV) market is at a crossroads, according to the conclusions of the recently-released NPD Solarbuzz North America PV Markets Quarterly report.

The addition of energy storage to an existing or new utility-scale PV installation allows system owners and operators the opportunity to capture additional revenues. Traditional storage plus solar applications have involved the coupling of independent storage and PV inverters at an AC bus or the use of multi-input hybrid inverters. An alternative approach - coupling energy storage to PV arrays with a DC-to-DC converter - can help maximize production and profits for existing and new utility-scale installations. DC-Coupled Utility-Scale Solar Plus Storage leads to higher round-trip efficiencies and lower cost of integration with existing PV arrays and at the same time, opens up new revenue streams not possible with traditional AC-coupled storage, including clipping recapture and low voltage harvesting, while being eligible for valuable tax incentives.
