Smart Grids Environment

smart gridSmart grid is a new technology. That is the centralized network connections, which are used as information and communication. So with this centralized concept can be more efficient and effective in communication of information technology. Some things about the smart grid related to the environment will be discussed later.

By increasing the level of information available to the people managing the power grid we can more efficiently adjust to meet peak demand. This is the first major environmental improvement that we could see from smart grids. Currently peak demand is met by running what are known as “peaker” plants. These are typically older coal fired power plants that only run to help meet peak demand. By more efficiently controlling our power grid through better monitoring we could decrease and possibly get rid of the need for these dirty power plants. However, new technologies must be implemented to allow for the monitoring and control of power to manage this peak demand. In addition to helping cut down on our environmental impact, decreasing the need for “peaker” plants will help decrease the cost of energy because we will no longer be paying to maintain power plants we only use occasionally. These same smart grid monitoring technologies will also allow grid managers to better respond to system overloads and route excess power to prevent outages thereby minimizing economic loss due to power outage.

Another goal of smart grid technologies is to increase the efficiency of cross continental power transfers through the grid. This will be a major step forward for renewable power sources, helping to alleviate some of the downside of intermittent production. Being able to effectively move power generated anywhere around the country we can have wide spread production of renewable energy insuring that some portion of it is always online. As it currently stands wind generation needs to be backed up by more traditional forms of generation incase the wind stops, however by dispersing our wind generation across the continent we decrease the risk that we will completely lose production. Along with this comes a greater possibility for a decentralization of power production, allowing for smaller wind turbines and solar arrays to plug into the grid and share the power they create.

There are also more consumer oriented ideas under the canopy of smart grid technologies. One which is already being implemented is the use of smart meters. Smart meters allow of dynamic pricing of energy based on current levels of demand. By increase the price in real time as demand increases we can help smooth out our power demand curve, which will help further alleviate the strain put on the grid during peak demand periods. Along with smart meters people are also developing smart appliances that monitor the demand on the grid and run when there is the most power available. This would include things like dishwashers and clothes driers that you could set to run overnight, but instead of setting an exact time, you would just tell them to run when the price of energy drops below a certain threshold. These consumer smart grid technologies will help consumers play an active role in power grid management instead of the current passive role they play now. Higher involvement with the community allows everyone to pitch in and do their part to help solve the current environmental problems, but it can’t happen without smart gird technologies.

The final aspect that smart grid proponents talk about is something that is already widely available to consumers but not taken advantage. I am referring to energy efficiency improvements. If everyone in the country did the most to make their homes as energy efficient as possible we could dramatically decrease the strain we put on the grid. By reducing our demand for power from the grid we would make it easier to transfer to renewable energy sources and manage our peak demand. While there are already many options available for improving home energy efficiency the goal of smart grid technologies is to increase awareness of these options and give people a reason to seek out problems and make improvements in their home energy efficiency.

This only covers the very basics of smart grid technologies as they apply to a wide range of topics. The overall idea of smart grid technologies though is clear; to increase efficiency and intelligence in the power system as a whole. Achieving these goals will make it easier to integrate renewable energy sources into our power system, deal with peak demand, prevent outages and build a more resilient power grid. So while smart grid technologies in and of themselves may not be considered green technology they will aid in allowing a speedy adoption of green production and thereby help reduce the production of Co2 and other pollutants.

Photography Tips for Newbies

Photography TipsPhotography can be a fun hobby. Result is not only a good photo can be from a good camera. But also there are some techniques that must be mastered. For those of you who are just trying to photography, there are some tips to be learned. Hope can be a useful and successful professional photographers.

Camera Controls

Although photography is often looked at as an “Art” where magic happens, if you don’t know how to use a camera then you won’t get anywhere. Fortunately, camera control basics are pretty easy to get a grasp on.

There are automatic controls and manual controls on each and every camera. Even phone cameras have some manual settings. In general, for photography training you’re going to want to learn what all the manual controls are and how to use them.

To start, there are two very important controls to know: shutter stop and aperture. These both control the amount of light let into the camera. By controlling both of these settings you affect the light exposure as well as the depth of field of the shot. In addition, you could do cool action shots at high speeds or shoot a photo at extremely slow speeds and make water look like clouds.

Your goal as a beginner should be to learn how to use an SLR camera on full manual. This means setting the aperture, shutter speed, ISO, focus, and a number of other settings. Don’t worry, it’s not hard. Once you get the hang of it it’s actually something you wish every camera had.

While automatic controls are very convenient, they prevent us from taking the photo that we imagine when seeing a scenery to photograph. Photography training enables us to see a scene, imagine how we want it in your minds, and then take the shot and match our vision to the end result.

Creative Composition

The next important part to photography training is learning composition, or how to properly arrange the contents within the screen of your camera. This is an ancient art with techniques and traditions dating back to the beginning of art history. The same techniques that apply to painting, drawing, etc apply to this. A good idea is to get some books on composition for any art (except music) and learn the techniques there.

Some basic examples are the “rule of thirds” and “leading lines”.

The Rule of Thirds – This rule states that instead of placing a subject at the center of the image, offsetting them to the left, right, top or bottom.

Leading Lines – Using the lines around you to point towards the subject of interest. Having the lines lead the viewer.

Although these examples are basic they do make a big difference in your photos if you’ve never consciously taken pictures with this in mind.

When you have both of these two parts of photography training down (composition and technical camera usage) you should have no problem getting better at photography. The next step from there is refining your style and developing your artistic eye.
