Now the other side of the Transactive Energy world is what you use as a renewable energy source. Today there are three options, one is extremely expensive, and the other two are fairly responsible for pricing. The expensive renewable energy source is the creation of energy using Geothermal power. While you can do it, you have to maintain a turbine and other technology to continue to generate power. The cheaper systems are wind power and Solar.
Let’s take a look at the two systems and discuss the pros and cons of both. First, let’s talk about Wind Turbines. The easy pro is they are easy to use and while they have an enclosed turbine are less expensive than the Geothermal power option. They have space requirements, and of course, they do require wind. That means in my subdivisions throughout the world, where houses are pretty close together the what and how of the yard alignment boxes critical. The wind has to blow! For larger plots of land, A Wind Turbine is a better fit overall. Let’s review quickly, pros you get clean, renewable energy. Cons you have to have enough space and enough wind to power the turbine. Wind turbines require batteries due to the nature of wind. It gusts (producing lots of power), but sometimes it doesn’ blow consistently. Wind turbines in subdivisions normally have to be on roofs. If you happen to have more land, then on top a hill if possible is optimal!
Solar power is a little easier. It can be mounted in your backyard, or on your roof. Obviously on the roof greatly reduces the overall impact of where the panels are. Like a wind turbine, the value of batteries for solar systems are critical. You see when the sun goes down, so does solar production. The other risk you have is that your Home Owners Association (or HOA) won’t approve or allow either a wind turbine or a solar panel. That is a fairly large risk overall. Pros for solar, they last longer than most wind turbines today (they being solar panels). Wind Turbines have moving parts and require more Maintainance, lasting 7-10 years. Solar panels last 15-20 years overall.
Both systems Wind and Solar have batteries that are easily installed. They, Wind or Solar, integrate with existing generations. You need a battery system to distribute the energy when there is no wind or when the sun is down. The value overall is the savings you get!
