Before I could even attempt to understand renewable energy, I realized how critical it was for me to understand the role energy, as a whole, plays in the world today.
At first glance, it is easy to think of energy simply as the ability to flick a switch at home and have a light bulb come on. When I talk about the energy industry with most people, they only see it as a local power plant that feeds electricity directly into their homes allowing them to have light, watch TV, run AC units, wash their clothing, and cook food in their microwave ovens. Even though they are not wrong, it is amazing how limited an understanding we, everyday people, have on the complexities of energy generation, distribution, and usage.
First, let's start from the beginning and consider energy generation.
This list is useful in giving us an idea on the different types of energy generation means utilized in the US and the respective amounts of thousands of Megawatts each one produces.
The chart is a screen grab from the excel file exported from the site and has been slightly formated to only include the relevant information for this Blog. (http://www.eia.doe.gov/cneaf/electricity/epm/table1_1.html) for Table 1.1 and http://www.eia.doe.gov/cneaf/electricity/epa/epat5p1.html) for Table 5.1
There are a few things that I would like to point out regarding these charts and map.
- Electric power is generated in many different ways.
- Total power generation has grown by 18% in the past 13 years.
- Number of power plants has not grown significantly in the same period (except for renewables).
- Power plants are scattered throughout the country.

In order for thousands of power plants to be able to generate power and distribute it all across the country, it is critical for an advanced and complex information exchange network to be available. It is at this junctions that realize how ICT is the indispensable component of the grid infrastructure that allows for electricity to be generated in different places from where it is consumed.
It is a common occurrence for one part of the country, on a hot day, to not be able to generate enough power to feed the local demand needed when all the air conditioning units kick on at the same time. This is why "peak" prices exist. As more and more power plants need to come on-line to meet this need, energy is traded in real time all across the country, and in many cases, across international borders.
In order for these transactions to occur in the mos efficient manner, highly advanced information networks need to be in place. These networks provide real time information regarding weather patterns, electricity market bids and asks, grid loading conditions, as well as the ability for companies to sell their planned production as futures.

I hope this was not too vague or overwhelming, every time you start digging into this vasts amounts of information comes your way. Now that we have a basic understanding on the production and distribution of power and the ICT infrastructure behind it, we are free to go one step further and in my next entry discuss how energy is used and how information and communication technology plays a role there too.
