Games on Disc More Energy Efficient than Downloads

“This research investigates the carbon footprint of the lifecycle of console games, using the example of PlayStation 3 distribution in the UK. We estimate total carbon equivalent emissions for an average 8.8-gigabyte game based on data for 2010. Two delivery scenarios are compared: the first examines Blu-ray discs delivered by retail stores, and the second, games files downloaded over broadband internet.”

“Contrary to current consensus that downloaded data will result in lower carbon emissions than distribution by disc, producing and distributing an average-sized game by Blu-ray disc in 2010 resulted in approximately 50 to 90% less emissions than downloading. The estimated carbon emissions from downloading only fall below that of Blu-ray discs for games smaller than 1.3 gigabyte. The study findings serve to illustrate why it is not always true that digital distribution of media will have lower carbon emissions than distribution by physical means when file sizes are large.”

Trolleytrucks in Los Angeles

siemens trolleytruck“A project testing a new way to power trucks with electricity is moving forward along selected highway lanes near the Ports of Los Angeles and Long Beach.”

“The South Coast Air Quality Management District, which is the air pollution control agency for all of Orange County and the urban portions of Los Angeles, Riverside and San Bernardino counties, has selected a company to install a catenary system.”

“This is essentially overhead electrical lines that supply trucks with electric power, similar to how modern day trolleys or streetcars are powered on many city streets.”

Animals as the Answer to Recycling Food waste

Mountains of food scraps end up in landfills every day. While northern countries glorify attempts to facilitate this trash-to-treasure process using state-of-the-art technologies, Bobbili, a town in Northeast India, adopts a tech-free solution – a park using animals for solid waste management.

Lost Crops of Africa

lost crops of africa

“Like Asia and the Americas, the continent of Africa is blessed with a rich tropical flora. Many of the 50,000 or so plants that evolved within its forests and savannas ripen fruits to tempt the myriad wild creatures into spreading their seeds. Speaking generally, Africa has as many of these tasty morsels as tropical Asia or America.

This fact, however, is something one would never guess by looking in produce markets or college textbooks. Today, American and Asian species dominate tropical fruit production worldwide, including within Africa itself.

For this, there is good reason. Africa’s fruits have not, by and large, been brought up to their potential in terms of quality, production, and availability. Geographically speaking, few have moved beyond Africa’s shores; horticulturally speaking, most remain poorly known. Thus, the vast continental landmass lying between Mauritania and Mauritius contains a cornucopia of horticultural, nutritional, and rural-development jewels still waiting to be cut and polished.”
