I don’t why, but it seems like I’m constantly changing light bulbs at my house. Normal incandescent bulbs last only a couple weeks in some of my lights meaning every other time I hit the switch it feels like I’m needing to pull out the stepstool and replace some bulbs. I would love to use LED-based light rather than the little florescent bulbs I’ve started using because I don’t care for the color of light they produce.
The problem is that most LED light bulbs are either too dim or too expensive for me to justify. Finally, LED light bulbs are beginning to come down in price and increase in brightness to the point where you can use them in your average light fixture. Home improvement center Lowe’s has a new line of LED bulbs sold under the Utilitech brand that are surprisingly affordable.
The company offers several different watt ratings under the Utilitech name including a 100 W equivalent. That 100 W equivalent bulb consumes 23 W of power and produces a warm white light color in the 3000K range. The bulbs are rather odd looking with a very large finned heatsink and the yellow protrusion where the LEDs are actually housed.
I’d like to see the bulb in a fixture to get an idea of how much of that is going to stick out or if it’s approximately the same size as a traditional bulb. With looks aside, the 100 W version sells for $34.98. That’s still pretty expensive, but it has a 25,000 hour lifespan meaning you won’t have to replace this bulb for years, in fact the manufacturer says 22 years. Perhaps even more appealing than the 100 W equivalent is a incredibly cheap 40 W equivalent sold under the same brand name that costs $9.98. That isn’t much more expensive than the small florescent lights on the market and you shouldn’t have to wait for an LED bulb warm-up the way you do a florescent bulb to get full light strength.

So, we did read about how Denmark intends to glean up to 50% of their national energy needs from wind turbines alone in a few years’ time. This is definitely a commendable effort, and are there any other kinds of green and eco-friendly ideas that the world could benefit from? Well, it seems that researchers have managed to generate hydrogen from any kind of plant, hence resulting in a safe, renewable energy solution. This particular solution was due to delving into a previous theory, where xylose, an abundant kind of sugar found in plants, is used to generate hydrogen. Since plants can be considered as a kind of renewable resource, you can more or less say that this is one method which is relatively safe for the environment.
What you see above might be just a concept at this point in time, an idea that has yet to be tested and proven successful, but assuming it actually takes off in due time, it could very well prove to be one of the modern engineering marvels that the world should emulate, especially the Danes who seem to be 
The Tesla Roadster can be said to be a dream car for many a Greenpeace activist, although for all intents and purposes, a hybrid like the Toyota Prius would be a far better bet. Well, perhaps it is time to see that the electric sports car market is maturing, especially when you see yet another competitor hit the scene after the Tesla’s Roadster production drew to a close at the end of 2011. Detroit Electric has just announced a different Lotus-based sports car which is capable of hitting 0–60mph in a matter of just 3.7 seconds.
Solar cells are a good thing, as they do their bit to make sure that the world is able to survive on renewable energy, but manufacturing solar cells are not exactly the most eco-friendly method of getting things done due to the kind of toxic waste that is a by-product of the entire process. Well, researchers from Georgia Tech and Purdue might have stumbled upon the Holy Grail, where they managed to create, what is potentially, green technology’s most renewable resource to date. We are referring to solar cells made from trees, now how about that? Not only that, these will be recyclable in something as normal as regular tap water.
What you see above is known as the Freeride E-Speed electric motorcycle, although it is right now still in the prototype stage, where the Freeride E-Speed hails from KTM-KISKA. It certainly is a beauty to cast your eyes upon, where it performs just like how a normal commuter would expect it to, and also has the capability of performing offroad as well, which means your weekends would be a whole lot more exciting.
