Poem

Look Outside, see the trees
Watch the flowers in the breeze
Things won't be like this in a year or two
If polluting is all we do
Seize the night
Seize the day
Things won't always be ..........

LED Light Bulbs

LED is short for light-emitting diode.  The LED light bulb was first made in the mid 1990’s. They are semiconductors that work by passing electrons turn into light. LED light bulbs are a little more efficient than CFL light bulbs because most of the energy is directed to light instead of heat. The LED light bulbs are heat sensitive so the bulbs have a Heat sink plate that moves the heat away from the bulbs, which is made by aluminum. Some of the common uses for LED's are for light bulbs at your home, lights in cars, and light bulbs in cell phones.

LED light bulbs also have a different color of light emitted by the bulb. Unlike the other 2 light bulbs, the LED lights give off a white or cool blue color which is just due to the fact that it’s the color the diodes give off. 

LEDs have also been given more features than just giving off light. A new light bulb that was invented was the lumen TL800 LED Smart bulb. Unlike the light bulbs we are used to, it has special features you can control. With the Lumen TL800 you can change the bulbs color, you can make the bulb brighter or dimmer, and it has a sensor that can make it change it sync to your music. It is Bluetooth so that makes it accessible from your phone.   

Hydrogen the Energy Source of the Future?

Hydrogen powered technology is a contraversial topic right now in technology. There are many good and bad things about having hydrogen become the next main source of energy in the world.
Hydrogen is probably the most ecofriendly fule avalible. Unlike fossil fuels, when cumbusted, hydrogen doesn't release any green house gasses into the atmosphere causing climate change. Instead, it produces water as a "waste". Also, you can get hydrogen by spliting water molecules into hydrogen and oxygen. Finally, Hydrogen is aproximatly 2 times as exxicient as fossil fuels.
Now for the downside. Production of hydrogen is quite expensive. In order to get hydrogen by itself, you need to remove it from a bond with another element, water being the easiest to obtain. Also, you spend more energy making hydrogen than you actually get by using it. Next, Hydrogen has to be kept in a low temperature and under high amout of pressure.
These are the good things and bad things about using hydrogen as a primary source of energy in the future.

Why Energy Efficiency?

Before viewing this blog, i would like the reader to understand the term Energy Efficiency. Energy efficiency is pretty much getting more out of sources of energy. Some people tend to mix up energy conservation and energy efficiency.
Incandescent light bulbs, for example,  are less efficient than fluorescent light bulbs. You get the same amount of light from both light bulbs yet, the florescent light bulbs use less electricity, making it more efficient. Turning off the light bulbs or using less light bulbs would be part of energy conservation, because you are using them less.
The reason why I chose energy efficiency is because I'm thinking about majoring in environmental science, in which becoming energy efficiency is one the goals. With this blog, I would like to show people how to save energy which will help them save some money and also help the environment.
