Climate Change

The Cool Earth concentrator design

There is no doubt that mankind stands at a pivotal point in our history in relation to our consumption of global resources and the resultant impact on the planet on which we live. By far the biggest concern is our ever-growing appetite for energy to power the lifestyles we have grown not only accustomed to, but also dependent upon. Solar is one answer with great potential, but economics and the amount of power it can produce in comparison to fossil fuel power stations has held it back so far. Now new approaches like Cool Earth’s collectors are becoming advanced enough to effectively tackle these problems with technology that relies on inexpensive and free materials, is scalable, able to compete economically with fossil fuel power plants and is capable of delivering not just megawatts, but gigawatts of clean power.  Read More

Planning ahead: US electricity generation sources

While the current Wall Street financial crisis has many on edge in regard to the short term future of the economy, Google has displayed some far-sighted corporate leadership in releasing its plan for how to reduce fossil fuel use by 2030. "Clean Energy 2030" is designed to stimulate debate on a range of energy consumption issues and includes proposals to slash vehicle oil consumption and CO2 emissions by 38% and reduce US reliance on fossil fuel-based electricity generation by 88% through a significant boost to solar, wind and geothermal output. Importantly, the report also focusses on the "win-win" potential for this aggressive attack on climate change, citing a figure of $1.0 trillion net savings over the 22-year life of the plan.  Read More

The craft, modelled on the Mars Reconnaissance Orbiter and Mars Odyssey, will arrive at Ma...

After the Phoenix lander has finished scraping away at Martian soil, the MAVEN spacecraft will examine the atmosphere of the red planet. The US$485 million Mars Atmosphere and Volatile EvolutioN program is the second stage of NASA’s Mars Scout program, following the successful Phoenix mission. The MAVEN craft will study the planet’s atmospheric gases, upper atmosphere, solar wind, ionosphere, planetary corona, solar EUV and SEPS, and investigate past climate change.  Read More

Sheraton’s Wild Horse Pass Resort

The Sheraton Wild Horse Pass Resort & Spa has launched a new initiative called GeoGreen which is designed to ensure environmental and cultural sustainability whilst maintaining the heritage and well-being of the Gila River Indian Community. Guests will find a restaurant menu featuring local ingredients sourced from Gila River farms, grounds filled with native plants watered by a timed drip system, local businesses being engaged in the process of keeping the resort green and will have the opportunity to be exposed to the culture of the Pima and Maricopa people.  Read More

Carbon Capture and Storage slashes CO2 emissions into the atmosphere, but requires an incr...

Carbon capture and storage is a climate change mitigation technology characterized by sporadic and unreliable government support and plagued with accusations that it will worsen the environmental disaster it seeks to address. Yet, despite the negative stigma, CCS has been labeled by the IPCC and the Stern Report as an essential measure in reducing the impact of fossil fuels. Gizmag's Kyle Sherer takes a closer look.  Read More

Nature's SUV in its natural habitat. Between 57.1 and 117.9 million metric tonnes of carbo...

A study published in the Institute of Physics’ Environmental Research Letters section today claims that by converting livestock manure to biogas, the United States could reduce its greenhouse gas emissions and generate up to 108.8 billion kW h – 2.9% of the country’s total electricity requirement.  Read More

The PANGAEA Expedition.

The 35-meter two master PANGAEA is the largest and most flexible polar expedition sailboat ever built. It can navigate through tropics and rivers as easily as it can through polar regions, and will travel to five continents, including the North and South Pole.  Read More

PEIR system screenshot

A key starting point to helping the environment is determining what impact we personally have on the planet. To assist in this challenge researchers at UCLA have developed a way to generate online Personal Environmental Impact Reports (PEIR) using location data from cell phones.  Read More

Burj Al-Taqa: self-sufficient skyscraper design

This concept eco-skyscraper from German-based architects Gerber Architekten combines traditional building ventilation techniques with the ability to generate 100% of its energy needs using wind and solar power. And the likely location for the "Burj Al-Taqa" or "Energy Tower” - you guessed it - Dubai.  Read More
