“A time to search and a time to give up, a time to keep and a time to throw away,” says Ecclesiastes.
For energy it may be: a time for coal and nuclear and a time for renewables. Keep reading →
IBM’s recent successful implementation of infrastructure for a smart grid throughout the Mediterranean island country of Malta may provide important lessons for other countries seeking to lower energy costs and reduce greenhouse gas emissions.
Some images from the project help illustrate why smart grid is becoming an increasingly attractive option for American utilities, power generators and consumers. Keep reading →
Weekly #Oil Analysis: Projected increase in world oil demand may require OPEC production increase http://t.co/VEaCrXi #energy @EIAgov
With their minds on a sustainable future, Dutch firm DSM and Skysail have looked to the past. The companies have taken a centuries-old approach to solving the fuel challenges of today’s cargo ships, reintroducing the use of sails onto massive oil tankers.
The kite sail doesn’t look a traditional sail on ships from the seafaring past. It attaches to a variety of vessels by a light weight tow rope made with Dyneema, which DSM says is the world’s strongest fiber. Shipping accounts for 90% of international trade and in turn is responsible for over 3% of World CO2 emissions. DSM and Skysail’s kite sail reduces fuel use and related CO2 emissions by 35%, the company says. Keep reading →
With a still lagging economy and increasing awareness of greenhouse gas emissions, many Americans are looking for ways to cut down on electricity use.
More than renewable generators, some say, energy efficiency is the more direct way to cut down on emissions created by burning fuel for power generation while also saving money. Keep reading →
Investing in clean energy is generally seen as nice to do, but rarely profitable when compared with dirtier fossil fuels.
But in the sustained search for returns that can show total growth beyond those produced by major equity indexes, funds are beginning to flow at an ever-accelerating rate into markets for clean energy technologies and the companies that develop and provide them. In a global investing environment, much of that funding is going abroad, raising concerns on Capitol Hill. Keep reading →
Big lessons can come from small places.
In 2009, the IT giant IBM agreed to transform the utility operations of a small Mediterranean island country, Malta, by implementing a national smart grid system for water and electrical use. Keep reading →
New terms are always emerging in the energy business. With GE‘s recent deployment of eight Aero LMS100 turbine-generators in a California natural gas plant intended to act as a partner to renewables by ramping up and down extremely quickly, “wind firming” is the latest term that has emerged in the generation business.
The CPV Sentinel’s eight turbines can reach peak capacity in 10 minutes and are therefore part of “wind firming” because they provide a back-up system for intermittent generation sources such as wind and solar. Keep reading →
GE is diving head-first into renewables generation. Keep reading →
