  • Time to export energy efficiency?

    We keep hearing that China is going to become a really big deal in world energy markets. But it wasn’t until I read this statement by Jane Henley, CEO of the World Green Building Council, that I grasped the scope of its coming influence: "China is projected to build the equivalent of 10 New York Cities over the next decade.” For some, such rapid economic expansion by China is cause ...

  • A combined electro-mechanical control technique for dynamic voltage regulation of a stand-alone wind turbine generator

    This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load voltage regulation. Speed regulation is achieved by adjusting the pitch angle of the turbine blades. ...

  • Size optimisation of hybrid wind-PV power generation systems for remote rural areas

    Electrical power generation with renewable energies, such as wind and solar, plays an important role in the electrification of remote rural areas. Since there are always seasonal and synoptic variations in wind and solar resources, a hybrid system, consisting of both wind and solar energy, may be more reliable and economical than a single energy system: this is because either energy can ...

  • How to make energy efficiency affordable

    Energy efficiency is a tortoise in the green energy race. Not glamorous like solar, wind or smart grid, it tends to plod along in the back of the pack, attracting little media attention. But being last can be a good thing; you learn from the frontrunners. Such is the case when it comes to financing. EE is beginning to borrow from strategies that have spurred tremendous growth for solar and other ...

  • Multi-criterion optimization of energy management in drinking systems

    In this study, two different energy sources that are connected to a pumped storage water supply system are analyzed: a water and a wind turbine. A water turbine can be integrated in a water supply system in high-pressure locations. Recently, new sources of energy production are being researched and applied due to the increase in the price of conventional energy sources and concerns regarding the ...

  • CSP Thermal Energy Storage vital for utilities and grid operators

    The modern age of CSP can arguably be traced back to the 354MW Solar Energy Generating Systems (SEGS) in the Mojave desert, which now make up the oldest operating plant in the world, as well as one of the largest. However, recent developments in the industry will see SEGS eclipsed by 5 projects that are scheduled to come online in 2013-14, with a combined total of 1312MW. The five plants in ...

  • As Global Demand for Electricity Grows, Geothermal Energy Heats Up

    January 9, 2017 — At 2:46 p.m. local time on Friday, March 11, 2011, Japan was rocked by the largest earthquake ever to strike its shores. The 9.1 magnitude quake triggered a devastating tsunami that killed more than 15,000 people. It also took out the back-up emergency generators that cooled the reactors at the Fukushima Daiichi nuclear power plant complex, causing a series of ...

  • Are you eligible for a manufacturing tax credit?

    The United States has been generous with tax credits for energy production. But until now, it’s been somewhat miserly about giving breaks to those who make the equipment that makes the energy – or saves it.That’s changed with creation of the Advanced Energy Manufacturing Credit (MTC), part of the federal stimulus package. The 30% tax credit makes $2.3 billion available for new, expanded, or ...
