Spain Leading Renewable Energy Generation

Posted on February 14th, 2011 by

Spain’s renewable energy portfolio getting stronger by the day, how clean energy is reaching the likes of Tanzania, and is triple paned windows overkill?

Spain Generates 35% Power from Renewables

Spain is making some of the world’s greatest progress in renewable energies, as clean energy makes up 35 percent of the country’s electricity. In fact, coal accounted for only four percent of the total electricity supply. This low figure is especially commemorative because children fear the gift of coal from the wise men on January 6. Tradition aside, Spain has been producing a significant amount of clean energy daily. Coal-fired power dropped by 34 percent last year. Gas-fired power dropped 17 percent, reducing CO2 emissions by 20 percent, according to GreenPeace.

Second Wind and Dartmouth Bring Clean Energy to Tanzania

Second Wind and Dartmouth College engineering students are working together to bring clean energy development in Tanzania. Second Wind has donated a wind data logger to the project to assess whether the winds in the region can consistently power a turbine and produce sufficient power. The proposed turbine would provide electricity to pump water and charge batteries and cell phones for residents of a small, remote village in Tanzania. Installation of the turbine will help Kigoma residents develop sustainability.

Triple Paneled Windows Reduce Energy Bills

Winter chills this season has convinced a number of homeowners to make their homes more energy efficient. One popular method is triple pane replacement windows for more insulation. Triple panes keep the cold out thereby reducing heating costs. The windows offer more surfaces for low-emissivity coatings so that the glass can reflect heat back to its source because of the thin metallic coating. This way, in the summertime, heat from the sun is reflected back outside and in the wintertime, heat from the house bounces back into the house. The coatings also protect from ultraviolet light and blocks infrared light that causes heat.

Puna Geothermal Enters Agreement to Hawaiian Island Grid

Puna Geothermal will provide eight megawatts of geothermal power at a fixed price for the next 20 years to the Hawaii Island grid. Puna is a subsidiary of Ormat Technologies and already provides about 30-MW to the grid under separate contracts. Hawaii Island is a leader in the use of renewable energy. One-third of the energy supplied to customers comes from geothermal, wind, hydro-electric and solar sources. Soon, biomass will also be added to the mix.

Continental Creates Safety Sensor for EVs

An international automotive supplier has developed a sensor for electric vehicles that will shut off the battery immediately after a collision. Continental created the evSAT to improve the safety of electric and plug-in hybrids so that emergency service workers can help accident victims without the risk of electric shock. The evSAT will go into production with a German vehicle manufacturer in 2012. The sensor will work during the vehicle’s charge mode where the accelerator sensor emits an algorithm to detect a collision and transmits a signal to the battery system and switches it off within half a second. The high-voltage battery is deactivated within four seconds at most.
