"LEDCentral.com.au is an Australian Owned and Operated Company, concerned with the environmental and economical impact standard lighting has on our planet today. Our goal is to save you money, whilst helping save our environment. Reduce your home and office lighting bills by up to 90% using one of the most efficient forms of lighting available. LED lighting uses approximately 10% of electricity than that of a standard light bulb. Energy efficient LED lighting creates less carbon emissions, which helps our environment as well as saving you money."

"In the 1900s, energy shortages led to breakthroughs in the use of fluorescents. In more recent years it has been all about improving affordability and efficiency. But what's the next bright idea in lighting? Organic light emitting diodes (OLEDs) are where it's all at. OLEDs are an emerging technology that deliver bright, thin, highly efficient displays with excellent colour purity. "

"RATEPAYERS are finally set to get some relief from soaring power bills with the rollout of LED street lighting. The state-owned electricity distributor Ausgrid - which owns and maintains 250,000 streetlights on behalf of 41 councils - has been trialling power-saving LED technology in Australian conditions over the past 18 months. Now councils across Sydney, the Central Coast and Hunter will become the first in Australia to be part of a grid-wide rollout of the energy-saving technology."

"GravityLight™ is an innovative device that generates light from gravity. It takes only 3 seconds to lift the weight that powers GravityLight creating 25 minutes of light on its descent.  "

"THE smelly scourge of suburban parks and footpaths could soon, literally, be seen in a whole new light. The contraption, called the Park Spark, was devised by a Massachusetts Institute of Technology graduate. Park Spark users put their dogs' waste in biodegradable bags and then into tanks, where a wheel turns to break it down and release methane, which powers a gaslight-style street lantern."

"This smart garden uses cutting-edge research in plant biology for higher yields, faster growth and more nutritious produce. It provides plants with the perfect amount of water, light and nutrients at up to 80 percent less than the cost to set up a comparable hydroponic or aeroponic system. It features professionally selected seeds that grow in the nanotech Smart Soil growth medium, ultra-efficient grow lights and electronic precision irrigation (EPI) that makes it possible to use up to 95% less water than traditional farming methods."

"It has been known for more than 150 years that light can have an effect on the electrical properties of some materials. This is called the photoelectric effect. In 1921, Einstein received the Nobel Prize for his work explaining this. Photovoltaic cells are based on a related phenomenon called the photovoltaic effect, and they convert light directly into electricity. Let's look at how."

"Shining a Light on Sustainability is an introductory video from the Australian Research Institute for Environment and Sustainability at Macquarie University, Sydney.  This video introduces the concept of sustainability and explains our current situation even before any potential challenges from climate change are involved. What does sustainability mean? Why are we currently unsustainable? What is an ecological footprint? What's the problem with plastic? What about water? And biodiversity? How are people faring? How can we find a sustainable path? What are some great sustainability initiatives?"

"The 2009 Green Light Report is a Victorian Government initiative detailing the environmental attitudes, behaviours and household features of Victorians."

"Plans, tools and information  to help you build renewable energy andconservation projects. Hundreds of projects -- from changing a light bulb to building a solar homes. Design information and tools  for building renewable energy projects. An Experimental section for backyard inventors. Nothing For Sale here -- just free ideas, plans, and information."

"Tony Abbott is facing growing discontent among his colleagues about his $3.2 billion Direct Action plan to combat climate change, a policy once described by Malcolm Turnbull as rubbish. Liberal MPs Mal Washer and Dennis Jensen say the Coalition should review or consider abandoning parts of the policy in the light of ''dire economic circumstances''."

"The Surf Coast council is planning to install solar panels on all its buildings to save power. The council has adopted a climate change policy for the next four years."

"As I write these words, 7.4 per cent of the electrons powering my laptop come from wind farms - travelling at the speed of light between hundreds of silently whirring generators and the complex electronics in my computer. The output of wind farms over the past nine days - the span of National Science Week - has been particularly excellent, and it's worth diving into some data to have a closer look."

Are you excited by insulation? No? Would you like a house with virtually no heating bill? Yes? Have you heard of a passivhaus? They're quite wonderful. A passive house (passivhaus) is a super insulated energy efficient home. The reason why you should want one is they have tiny heating bills, minimal carbon footprints, are flooded with natural light and enjoy superior levels of comfort to normal homes.

"Along with being a fun holiday for tricks and treats, Halloween is an opportune time to shine a ghostly light on the evil energy vampires lurking in homes. Those ghoulish fangs - also known as plugs in the wall - suck frightening amounts of electricity all night (and day) long, even when bloodthirsty electronics and appliances are turned off or doing nothing useful. The chilling truth is that as much as one-tenth of the electricity devoured in our homes vanishes as "standby power" - electricity feeding perpetually plugged-in electronics and appliances even when they're idle for long periods of time, like in the dead of night."

I've been trying to find info on what to do about replacing halogen lights for ages - this looks like it!
