Ormat Technologies, Inc. announced this week that it has signed a 20-year power purchase agreement (PPA) with NV Energy, Inc. for the purchase 30 megawatts (MW) from the McGinness Hills Geothermal project, which is currently under construction.
The PPA is subject to various approvals including the approval of the Public Utilities Commission of Nevada and is projected to come on line in 2012.
When completed, the McGinness Hills project will increase the total output supplied from Ormat to NV Energy, Inc. to approximately 135 MWs, helping NV Energy to meet its renewable energy requirement. Nevada’s renewable portfolio standard legislation requires 15 percent of all electricity generated in the state to be derived from new renewable energy sources by the end of 2012.
The U.S. government has identified 4,100 contaminated industrial sites, covering more than 5 million acres, suitable for building wind, solar, and geothermal power installations.
With concern about renewable energy projects being built on pristine lands, the construction of wind and solar arrays on idle industrial “brownfields” could be an ideal solution, according to federal officials.
The Daily Climate reports that the U.S. Environmental Protection Agency and the National Renewable Energy Lab will begin conducting detailed studies of some sites this month and will hold five workshops with state and local leaders, renewable energy developers, and conservation groups to discuss constructing alternative energy installations on brownfields.
A $17 million renewable energy project designed to tap into the earth’s heat more than 2 miles deep has been suspended because of difficulty drilling through rock formations.
The project, run by AltaRock Energy and partially funded by Google, was designed to drill down to about 12,000 feet, fracture rock at the bottom of the hole, and then circulate water to create steam.
But the company reported that it had encountered “anomalies” in the rock that had prevented it from drilling deeper than 4,000 feet.
California, which has often led the nation in emissions reductions and environmental initiatives, is not the standard bearer in producing renewable energy today. If you consider all forms of renewable energy — solar, wind, hydro, and geothermal, then California isn’t at the top in total production, and as a percentage of energy produced, it’s not even in the top five.
Washington, with its longtime investment in hydropower, produced nearly 58 percent more renewable energy from electricity than California, according to 2007 data. In California, 25 percent of all energy produced comes from renewables, which is lower than Idaho (84 percent), Washington (77 percent), Oregon (65 percent), South Dakota (50 percent, Maine (49 percent) and Montana (34 percent). Note that this is electricity generated not consumed. Many of the upper Midwest states actually export energy, while California imports the most energy in the country.
Water technology, solar innovation, Israel’s electric cars: I’d originally written this story for ISRAEL21c a few months ago when we were planning on launching its new Environment channel. The new channel was finally up this week. Consider it a good starting point if you’d like to know more about Israeli technology and investment opportunities and what the future may hold:
When green evangelist Al Gore visited Israel last year (and Green Prophet was there) he gave a clear message. “The people of Israel can lead the way to renewable energy,” he told audiences. With its unique geographical position, and clean tech know how, he announced, Israel is a natural leader in the field.
It’s a view that is echoed by many. Ian Thomson, the Californian co-founder of CleanTechies, a web site launched for clean technology professionals, agrees.
The goal is to enable power generation from low-temperature geothermal resources at an economical cost. In addition to being a clean energy source without any greenhouse gas emissions, geothermal is also a steady and dependable source of power.
A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) are testing a new innovative approach to safely and economically extract and convert heat from vast untapped geothermal resources.
“No doubts remain. Climate change is real and the build-up of greenhouse gases in our atmosphere is increasingly at an alarming rate.” With these words, Rafael Quiroga, General Manager of Accion RSE, initiated the seminar “Corporate Strategic Management of Climate Change and Greenhouse Gas (GHG) Emissions.” This is not another “green business” seminar from a European or North American city, it took place here — in Santiago, Chile.
The event brought together speakers from the Chilean private sector that gave concrete examples of their companies’ climate change and GHG management initiatives. First, it showed how Essbio, a water purification company, has been dealing with the ever-prescient and escalating challenges of decreasing water reserves due to climate change. Second, it illustrated the emissions and energy reductions Xstrata Copper, a mining company, has committed to and the steps it has taken to minimize the release of contaminants in its industrial processes. Third, it explained what Natura cosmetics has done since 2007 to become a “carbon neutral” business by calculating all GHG emissions in the company’s supply chain, transportation, and production of its various cosmetics products, and purchasing the equivalent amount of CO2 tonnage in carbon credits on the international carbon markets.
As a recruiter, I’ve had countless conversations with excited, motivated and very eager people that are looking to break into Clean-Tech. Like many, they are looking to do something more meaningful at work and something that transcends and has a deep impact. Another group of job seekers, and they are not necessarily mutually exclusive, are those eying the Clean-Tech space as a potential island in a very tumultuous economic sea.
Unfortunately, it is hard to assess just how much value you can provide to a sector that you know very little about. I will put forth that for a cash constrained company, it is difficult to project how success in an unrelated industry might translate to success in the industry they operate in.
The week before last was the culmination of a labor of love for Sunil Paul and Claire Tomkins with the launch of the Gigaton Throwdown in DC after 18 months of hard work, researching and – as I witnessed first hand – coralling the efforts of other researchers.
What is the Gigaton Throwdown?
The Gigaton Throwdown Study was launched as a Clinton Global Initiative in 2007. It was started as a project to educate and inspire entrepreneurs, investors, and policy makers to think big about solving the climate crisis. It was an effort to answer Sunil’s question, “What does it take to make a difference with clean energy technology?”
When we talk about wind, solar and geothermal power, geographical conditions such as surface areas and sunny latitudes are very important. Turkey offers excellent conditions for all of these renewable energy sources. Its young population of 70 million – 61% are under the age of 35 – and its strategic location between Europe and the Middle East, add to Turkey’s potential for a leading green power nation.
As Turkey aims at taking its place among the top-ten biggest economies by 2050, an increase in its energy consumption is inevitable. Electricity demand has been growing with an annual rate of 6.5% since 2002, up to current levels of 198,000 GWh/y. Scenarios forecast a 6% growth rate until 2020, compared to growth rates of 1-3% in developed countries. However, Turkey’s growth of electricity supply barely matches its fast growth of demand. The country began experiencing shortages already, and power has become a more popular daily topic.
In a sign of the growing importance of renewable sources of energy, global investment in wind power, solar power, and other alternative forms of energy last year exceeded investments in coal, oil, and carbon-based energy for the first time.
Ormat Technologies is combining with Itochu Corporation to build a 330 megawatt (MW) geothermal power plant in Northern Sumatra, Indonesia.
The project will cost an estimated $800 million, according a report in Reuters. Ormat and Japan’s Itochu Corp. were originally awarded the contract in 2006 and are working in collaboration with Indonesian energy firm PT Medco.
