The electricity you use to power your home is most likely generated by burning coal, with some nuclear and natural gas-fueled current in the mix for good measure. However, that could all be changing, and faster than anyone expected. While renewable fuel sources like solar and wind power make up only a small part of the nation's electrical grid today, wind could actually be the leading source of electricity in little more than three decades.

Viable and Competitive

Wind could surpass other sources and provide as much as a third of the United States’ electricity by 2050, according to a report by the U.S. Department of Energy (DOE) Wind and Water Power Technologies office. Wind currently weighs in at only 4.5 percent of the supply, but if projections hold, that will increase to 10 percent by 2020 and 20 percent by 2030.

“The wind industry can be characterized by the substantial growth of domestic manufacturing and the level of wind deployment seen in recent years,” José Zayas, director of the DOE Wind and Water Power Technologies office, said to EcoWatch. “Wind power systems are now seen as a viable and competitive source of electricity across the nation. Wind power’s emerging role is an important option in a portfolio of new energy solutions for future generations.”

Benefits to Public Health, Environment

Should the prediction of wind's dominance come to pass, it would have numerous benefits for the environment and for consumers. Even at current levels, wind has reduced water consumption by 36.5 billion gallons and carbon emissions by 115,000,000 metric tons compared to traditional power sources, according to the government.

That means a lot less carbon getting released into the atmosphere, helping to slow our contribution to climate change. Plus, once the infrastructure is built, wind is free to harvest, and doesn't have the same environmental tradeoffs as coal and natural gas. The benefits “can address key societal challenges such as climate change, air quality and public health, and water scarcity,” the report said.

Uncertainties Looming

The rosy projection is just that. There are numerous uncertainties that could affect how well wind power actually does in the future, including government policies to incentivize wind or decentivize coal usage, the supply and price of natural gas, and the demand for electricity overall in the United States.

The technology around wind generation will have to hold its own as well. Growth in market share depends on continued advances in efficiency, more transmission capacity and better weather forecasting so we can best take advantage of favorable gusts.

Global Optimism

Should the growth of wind continue as predicted, there could be hope for a cleaner, healthier future. And what's good for the United States can be good for the rest of the world as well.

“The global energy market of the future is poised to be the largest market the world has ever known,” Secretary of State John Kerry said in a speech about wind power. “Pursuing cleaner, more efficient energy is actually the only way that nations around the world can build the kind of economies that are going to thrive for decades to come.

Extension cords a quick tool that solves a lot of problems. Whenever we are at a lack of outlets, or need to use a device just a bit farther than the normal outlet can reach – extension cords are our best friends. But it is important to remember that extension cords were made for a specific reason, and using them incorrectly can lead to serious electrical hazards. Know the hazards and how to avoid them.

If you can identify with any of these hazards in your home it may be time to install additional electrical outlets to reduce dependence on extension cords. For assistance from a licenced electrician, contact Expert Electric at 604-681-8338.

The relationship between weather and energy usage is a never-ending cycle. Spikes and drops in temperature and humidity lead to spikes and drops in energy use (and costs), which in turn correspond with spikes and drops in greenhouse gas emissions, further affecting climate. What does this relationship mean when it comes to your energy usage?

Temperatures above 100 and below 40 stress your heating and cooling system, pushing it to capacity, reducing efficiency, and draining energy supplies, along with your wallet. Quite simply, this amounts to less bang for your buck in terms of comfort. Add to temperature issues, wind, cloud cover, and precipitation and the snowball effect continues, further impacting comfort levels, not to mention your ability to illuminate interior spaces. Compound the issues – and the population affected – and you’ve got grid strain to boot.

That depends on the source of energy. In the US, 83 percent of energy usage comes from fossil fuels, which release gases such as CO2 into the environment during the creation of energy. Unfortunately, these gases trap heat in the atmosphere. Atmospheric greenhouse gases have increased 30 percent since the pre-Industrial Revolution era alone, and the level continues to rise with energy demand. As levels increase, so does the effect on the environment. Thousands of scientists agree the trapped gases are currently affecting the climate, and will increasingly weigh on it as time goes on. This has resulted in an increase in interest in cleaner forms of energy, including nuclear, solar, wind, and geothermal.

We all want the best for our children, and one of the most important ways we can help the next generation is by ensuring that they are receiving the highest quality education they can. But what if I told you there is an element to education that most people overlook when discussing ways to change education, even though it has been proven to improve behavior and focus, reduce disruptions and increase reading speed and learning capacity?

Though often overlooked, Research has shown that full-spectrum, cool white light is best for encouraging concentration in a classroom, so swapping out outdated fixtures for newer technology could be a great start to better classroom lighting.

Although fluorescent fixtures are popular in schools, the way they flicker (often imperceptibly) especially if a child has a visual impairment that necessitates a brighter environment. Try to position the lights (or the students) so that the task lighting is on the opposite side of their dominant (writing) side. This ensures that their writing arm won’t block the light, and distracting shadows won’t affect their work.

Teachers should try to avoid standing in front of lights or windows when talking, because these can easily distract or bother students. Though it can be difficult, students will focus and learn better when the teacher eliminates as many distractions as possible. And who among us hasn’t caught themselves drifting in a daydream out a window, whether interested in the topic at hand or not?

There are many programs and initiatives for better classroom lighting in place, though many are local to specific regions. Have you heard of any neat programs geared towards smart classroom lighting? Let us know in the comments!

I have a great deal of interest in digital photography, but my life is as crazy as anyone else’s. My son, family, and work keep me busy from dawn to midnight every day. I’ve never had time to cultivate any photography skills, even though I’ve always been very interested, sitting on the edge of my seat, if you will, for a chance to take some digital photos in order to learn a little about how capturing light can create astonishing works of art.

My interview with Matthew Danser had given me my long sought “excuse” to try out some photography techniques. But it also required that I put in an honest effort. The thought in the back of my head: These photos are going to suck. Probably a lot. And they will most likely be seen by the thousands of people who visit this blog monthly. Second gulp.

But I’m the kind of person so riddled with ADHD that even my paranoia about being judged on a mass scale can only last about three minutes before the audacity to try anything resurfaces and action is taken. So here’s what happens when a total amateur who has no idea what he is doing tries to “Paint with Light.”

A one-dollar flashlight from – you guessed it – the Dollar General. One dollar. Even. Gotta love it. Especially since it’s all I could afford, seeing as how I’m still paying off the aforementioned Nikon that I bought to take photos of our baby son. (True, a million pictures have been taken of him during his first year-and-a-half on Earth. However, 999,999 of those photos were taken with an iPhone. Go figya.)

THE PLAN, STAN:

The plan was to wait until it was dark in the apartment and do some light painting. I knew that I could use the Shutter mode on my camera to set it to take exposures of up to thirty seconds. I saw that my camera also had an option for bulb release, so, invoking Danser, who recalls how his girlfriend had to hold down the button on his camera for a full thirteen minutes, I determined that if I asked really nicely, I might be able to persuade my wife to hold down the trigger to get exposures longer than thirty seconds. Otherwise, thirty seconds was my window of time to do all the light painting I could.

I started off pretty timidly. I had seen photos online in which people used long exposures to create squiggly lines. The most popular examples are pictures of traffic at night, headlights and tail lights streaming, giving you a sense of the fluid motion of busy intersections. You’ve also seen those nature pics in which streams and rivers and clouds and stars become gauzy with movement because of long exposures.

But what I really like about Danser’s work is the use of color. The effect of running inside the hut and popping off red-gelled flashes shown at the beginning of this blog post (Matthew Danser! And happy lightpainting, everyone!
