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!
I like them both and they complement themselves. You don´t have sun all the time and you don´t have wind all the time so… If I could I´ll have them both.
Very true points! Both add value or one with a battery system also would be the way to go.
I am in favor of the solar panels and one day will have them!!!!
I would love to see them on every single roof. WIth the new Tesla solar roofing tiles, we may yet realize that dream!!!
Whenever the master of technology speaks, it means valuable information that should not be ignored and important to note!
You flatter me Albert. I thank you for your kindness however.
I just said what I thought is, Coach!
Thanks, Albert. You are a kind person.
Well i am also planning for solar system .
That is great! congrats! It is a great way to make the world a better place.
Solar power for me. Although rains might disrupt them, they have little impact on the environment.
In heavy rain a solar system runs at about 40% production. That is still more than 0!!!
Thanks for that information. I always thought in rain, it will shut down. Now I know better.
There is still solar power coming through the clouds, just sadly less.
Very interesting information!
Thank you very much for your kind words!
I am in favor of the solar panels and one day will have them.
Solar City will install them free and reduce your power bill by a whole lot. Plus you don’t have to have 30 grand to cover your house!!!
Well done! Nice post!
I hope this isn’t a spam comment.
Given that our friend GT rarely says anything else, it probably is!
I know I shouldn’t be frustrated by that behavior. I try (and I know you do as well) to create unique and specific comments for each post I read.
I see that you are talking about these as possible resources for home use, as opposed to generators of electricity for industrial or grid use, where the factors will be different.
For home use, solar panels are going to be more practical for most people, which is why you see far more roofs bearing solar panels than you do wind turbines in back gardens.
One factor to bear in mind is the effect on wildlife. Apart from the danger to birds of spinning turbines, the noise they make could scare them off.
Actually the factors for business use of solar is only different from the array placement. Many companies have roof space that can be used. Heck, just planting green plants on top the building reduces the overall cost of power for that building (reduces the cost of cooling by 10-15%).
The best wind turbines are fairly quiet. But I do agree there is an impact on birds. Most of them are mounted on roofts, and have an enclosure that prevents birds getting killed. It does reduce the effectiveness of the turbine however.
I was thinking more of the difference between the use of such installations by individuals (whether homes or small businesses) and by wind farms and solar farms.
The UK is doing its best to cut out all coal-fired power generation, which means greater investment in wind and solar. Some of the biggest wind farms are out at sea.
I understand that point, I am more concerned that we haven’t come to the realization that simply saying you build a building, you have to put solar on it, is a simple answer. I worry that we aren’t there yet.
As for the reality of solar or wind farms, they truly are a different beast. The US Government actually created an agency (BOEM) focused on the wind power auctions.
Not every building is suitable for solar – if you don’t have a roof area that faces south or southwest, your panels won’t collect much sun.
