Question by bob d: questions about atomic energy? I’m wondering about multiple things. atomic questions———————————- 1.When it comes to atomic energy,it seams like the media demonizes atomic energy,is that true? 2.Did the Chernobyl incident “happen” due to the disabled safety features? 3.Did the power plant had a containment “dome”,like all power-plants today? 4.Why does the

Question by Ottawa Mike: Is the climate change issue really about a push for renewable energy? Here is the scenario as I see it: We are being told to reduce CO2 emissions because they will contribute to catastrophic anthropogenic global warming. To achieve that, we are basically being told (forced?) to reduce coal and oil

No maintenance or fuel cost. You still have to deal with theft and vandalism however.

Advantages of Solar power –
(a) The major advantage of solar power is that no pollution is created in the process of generating electricity. Environmentally it the most Clean and Green energy. Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
(b) Solar energy does not require any fuel.
(c) It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulfur dioxide or mercury into the atmosphere like many traditional forms of electrical generation does.
(d) Therefore Solar Energy does not contribute to global warming, acid rain or smog. It actively contributes to the decrease of harmful green house gas emissions.
(e) There is no on-going cost for the power it generates – as solar radiation is free everywhere. Once installed, there are no recurring costs.
(f) It can be flexibly applied to a variety of stationary or portable applications. Unlike most forms of electrical generation, the panels can be made small enough to fit pocket-size electronic devices, or sufficiently large to charge an automobile battery or supply electricity to entire buildings.
(g) It offers much more self-reliance than depending upon a power utility for all electricity.
(h) It is quite economical in long run. After the initial investment has been recovered, the energy from the sun is practically free. Solar Energy systems are virtually maintenance free and will last for decades.
(i) It’s not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing price of fossil fuel.
(j) By not using any fuel, Solar Energy does not contribute to the cost and problems of the recovery and transportation of fuel or the storage of radioactive waste.
(k) It’s generated where it is needed. Therefore, large scale transmission cost is minimized.
(l) Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage.
(m) A Solar Energy system can operate entirely independently, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations, making it more practical and cost-effective than the supply of utility electricity to a new site.
(n) The use of solar energy indirectly reduces health costs.
(o) They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel.
(p) More solar panels can easily be added in the future when your family’s needs grow.
(q) Solar Energy supports local job and wealth creation, fuelling local economies.

Hi Joe
Great question. I agree with the post of our friend Partha and I add this benefit:
- You Can Build Your Own Solar Energy Even if You Have No Solar Experience.
I think there are people who cannot pay thousands of dollars for solar energy ($ 27,000 average cost).
So, I thing that a real solution is to teach anyone to build your own solar panel system for just a fraction of the retail cost.
I’ve learned to build my own and now I can help my friends do the same.

It doesn’t produce pollution.

I’m going to give a strange answer.
What is best from one viewpoint is worst from another. Solar is a source of power that can be harnessed by an individual. As such, it is hard for a central entity to control. That’s good for the individual. I would pay taxes and distribution charges if I used an electric dryer, but if I use a clothesline, it’s free. I would pay a taxes and a surcharge on the natural gas to heat my water, but if I run a solar water heater, I’m free of that. It’s bad for a company trying to make an ongoing profit off of solar power, unless they are selling the equipment.

The best thing about solar power is that it is a renewable resource, which means it is a never ending source of energy. Solar energy is gaining popularity and is used in many industries and homes too. It has many advantages and is used to power small appliances, cars, cooking, and heating water…It helps to save water and money.

Hey Joe, it’s a harder question than most people think. Like everyone else here, I can list a dozen reasons, but to narrow it to one is challenging.
We live in a home now that is powered by the wind and sun. Our water is partially heated by the sun, and the house has some solar gain. Being free of imported oil, reducing pollution, distributing power sources rather than concentrating them as in the use of a power plant, all good reasons. Here’s mine:
Solar power gives us the power to live a healthier lifestyle as a society, here’s how. We can distribute our power by using a little solar array on each house, thereby reducing the need for such a large, cumbersome grid we have to look at and maintain. I for one would love to take all those coal miners out of the hole in the ground that they keep getting killed in each time there is an accident and put them to work building solar panels. Using solar power efficiently requires us to make some small habit changes, like using appliances in the daytime more often then at night, this allows the panels to run washers and dryers and vacuum cleaners directly from the sun rather than charging batteries to run them at night. You get more bang for your buck this way because there are losses charging and discharging batteries. The human body has evolved to function better during the day, it’s when we should be up working and socializing, not running household appliances at night. We can still do that, but we have found that by keeping our solar power in mind, we tend to wait until morning to get things done at our house rather than, “burning the midnight oil.” Jobs that are created in making solar power are higher tech and require more training than jobs in oil, coal and gas mining, so we could become a more educated society by simply doing more solar.
I could keep going, but you get the idea. There are entire communities that run on these principles now, like Stealth, Illinois, each home has a solar array, there is a common wind turbine and a larger array on the post office roof, and they all share the power that they produce. They share gardening space and other functions.
A couple good publications on this are Home Power Magazine and Backwoods Home Magazine. I would suggest looking for them in the library or subscribing yourself. You might end up with a solar home like ours someday, or you might not want to, and that’s fine. At least you will be well informed. Take care, Rudydoo
