India’s government announced a major commitment to energy efficiency earlier this year when the Domestic Efficient Lighting Programme (DELP) was launched, calling for 20 million lightbulbs in streetlights to be replaced with LED bulbs. The largest project of its kind, the upgrades will take about two years to complete, and comprise part of a larger effort to reduce the national power load and save hundreds of millions of dollars a year.

How Does Your Electricity Use Compare to the Rest of the World?

The United States has been doing a good job of cutting carbon in recent years. Emissions are down 12% in the last 5 years, and half of those cuts have come in the power sector where natural gas, wind and solar have been replacing coal. But when it to comes to electricity emissions from the home, we still have a lot of work to do. In a comparison of sixty countries, we found only Saudis have bigger electricity footprints. The average American uses 4,700 kWh in the home each year, costing them $600 and generating almost three tons of carbon emissions. Getting smart about tackling your electricity use can slash both your power bill and your carbon footprint. Learn more at Shrink That Footprint.

INFOGRAPHIC: How You Can Make Your Home More Energy Efficient

Energy Efficiency Buildings

Computer equipment and residential electronics represent 15 percent of the energy that residents consume worldwide, and that number is expected to triple over the next couple of decades unless steps are taken to improve energy efficiency. After computers, services such as lighting, air conditioning, electric heating, and large appliances are the next biggest culprits. Steps can be taken to make your building more energy-savvy, from turning off all electronics and lights when they’re not in use to taking the stairs instead of the elevator, and improving insulation in order to reduce heating costs. Check out the infographic after the break for more tips on how to increase the energy efficiency of your home or office building.

Power Plants: Scientists Grow Conductive Wires in Living Roses

[ By WebUrbanist in Conceptual & Futuristic & Drawing & Digital & Technology. ]

A group of Swedish scientists has developed a successful method for integrating conductive wire systems into plants, naturally soaked up from a gel into leaves and stems to create complete circuits in bionic hybrids. The implications, like the currents, run in two directions: power can be harvested from plants, but the plans can also be changed through the application of external energy.

Marks & Spencer recently announced that it will be installing the UK’s largest solar roof by mid 2015 at its distribution centre at Castle Donnington. The roof array will be linked to one of Europe’s largest solar thermal walls, which when combined will make the site close to self sufficient during daylight hours. ‘This further enhances the sustainability credentials of our BREEAM Excellent Castle Donnington site’ says Director of Property at M&S, Hugo Adams.

World’s Brightest Flashlight: Brilliant 1000-Watt DIY Lantern

[ By WebUrbanist in Gadgets & Geekery & Technology. ]


Lighting up the night sky like artificial lightning, this incredible homemade lamp boasts a 90,000-lumen output (over 100 times that of a typical Maglite) that would put the flashiest high-beams on dark roads to shame, making nighttime scenes look uncannily daylit.

Constructed by RCTestFlight and published on YouTube, the project consists of ten 100-watt LEDs mounted on a heatsink and powered by twin 8 amp-hour, lithium-polymer batteries (about the equivalent energy of 10 mobile phones).

Creative Lamp Design by Silvia Ceñal Idarreta

Sometimes simple designs inspired by everyday things may prove as functional as the more sophisticated ones, and with a high aesthetic value if you are a fan of handmade-looking objects and creative lighting design. The latest project of Spanish designer Silvia Ceñal Idarreta is an eye-catching hanging lamp, simply called Macaron Lamp.

Discovering everything that could be done with fabrics and laces and fascinated by the traditional French pastry called macaron,  Silvia Ceñal Idarreta imagined this interesting pendant lampthat once established in a certain decor, it’s likely to grab all attention due to its colorful and unusual design. She originally combined wood with wires, which transmit a feeling of three-dimensional.

The bulb was subtly added in the middle of the design, the overall look inspiring playfulness creating an interesting optical illusion by making you believe its body isn’t supported by anything and levitates around the bulb. But in fact body is upsholded by a round wood top, invisible when viewed from the front. Creative, isn’t it?

Striking another blow to the oil and gas industries, an American solar company has developed technology that can produce super-efficient solar power that’s cheaper than fossil fuels. Rayton Solar’s new solar panel manufacturing technology that uses 50 to 100 times less silicon than other technologies, cutting out large amounts of the most costly component of solar panels. The company says its patent-pending process uses just four microns worth of silicon, leaving no waste – while boosting efficiency to 24 percent. That’s 25 percent higher than industry standard efficiency, according to the company

Urban Off-Grid: 12 Creative Solutions For Self-Sustainability in the City

[ By SA Rogers in Architecture & Houses & Residential. ]

Off-grid housing is almost always relegated to remote areas due to strict urban building codes and access to affordable land, but sometimes self-contained structures pop up in parks, on rooftops and in canals anyway – or the owners of more conventional city dwellings simply cut the cord. There are already a lot of different ways to go off-grid in the city, most explored by necessity due to poverty, others seeking a more sustainable way of life without giving up community and convenience. From rooftop structures and mobile housing to entirely new self-powered city blocks, these solutions work within cities that already exist rather than envisioning expensive futuristic eco-cities from the ground up.
