How do you feel about using sola-powered appliances or other installations at home?
Hello, I’m a student conducting a short open-ended survey to get a feel of how solar-powered installations at home will be perceived and received by the average person. Your responses will help me develop a sustainable product for residential use. Feel free to respond and send me your comments. Thank you very much for helping! – MariaCGL
I have lived off-grid for about four years relying completely on solar electric power. I learned a lot about conservation as my system is very modest, but I wouldn’t exchange it for a monthly electric bill-I own my power not rent it from an electric company that can hike rates and pollute the air as much as they please.
I feel that utilizing solar energy has helped me look at my energy use in a new way. I have developed a new pattern language in my home and during my daily activities that have made me much less wasteful. Solar energy is expensive and so being efficient always trumphs adding solar modules to the home.
It feels great to use renewable energy from the sun!
What is an environmentally sustainable society?
What is an environmentally sustainable society? Distinguish between living on the earth’s natural capital and living on the renewable biological income provided by this capital. How is this related to the sustainability of (a) the earth’s life-support system and (b) your lifestyle?
It’s one where all the people are dead.
People have no right to live. It’s bad for “the environment”.
The government has a right to total power. If it’s necessary to pass laws that stop agriculture or the production of energy, that’s fine – anything for the environment.
You have no right to a lifestyle because it uses natural resources.
Don’t laugh. This are exactly the belief underlying the environmental movement, and which big governments throughout the western world are actively implementing.
The point is, the distinction the question asks about, cannot be made except by a society based on the private ownership of the means of production. Capital is a market concept. There’s no use talking about government management of capital, because government has no way to calculate capital without using market methods. Government has no way to not consume capital – in fact, that’s all that government does. There is simply no evidence or scientific reason for the modern superstitious belief that government can further environmental sustainability. The belief that it can is merely confused, like the person who wrote the questions you are asking.

How to become a green energy engineer?
I want a job that means something. Not just getting through it to get a paycheck. So this is why I chose to work with renewable energy. I’m just not sure what steps to take to get where I want to go. I can’t find any college around here (Columbus, Ohio) that can give me the courses needed. Maybe I’m not using the correct terminology to search for the classes. But I need any intelligent person to help me please!
Register here https://www.coursera.org/ and here https://www.edx.org/ and try find course about green engineering.
What specific training or degrees are emplyers looking for when it come to LEED/ Alternative/Renewable Energy?
I am looking for specific details of how to pursue and crosstrain into Alternative/Renewable energy fields of solar, wind, geothermal, and hydorenergy.
I have been in Stationary Engineering for 16 years so, I am looking to be able to install, repair, and be hands on. I also want to be able to design and then install.
What kind of job would you like to do? There are a lot of different people working in alternative energy. It’s like saying you want to work with food–do you mean a farmer? A chef? A grocery store manager?
With alternative energy, you could be an investor who funds the technology, an engineer who designs new technologies, an advertising agent who markets the technologies, a lawyer who works for those companies, the guy working under the sun who physically installs them, etc. Etc. Etc.
What is your background now, and in what capacity do you want to work in alternative energy?

Suddenly Switching from gasoline based automobiles to electric powered. How would it affect our economy>?
I was chosen to pick a topic for debate for an English class, and I decided on whether or not switching to electricity based automobiles would be a smart thing to do if we had the option. I have to include such factors as economy, jobs that could be lost with the loss of oil companies, impact on the environment, etc. Any online sources would be greatly appreciated.
Also definitely gonna give a best answer to someone who answers, so please help!
The electric car was among the earliest automobiles — small electric vehicles predate the Otto cycle upon which Diesel (diesel engine) and Benz (gasoline engine) based the automobile. Between 1832 and 1839 (the exact year is uncertain), Scottish businessman Robert Anderson invented the first crude electric carriage. Professor Sibrandus Stratingh of Groningen, the Netherlands, designed the small-scale electric car, built by his assistant Christopher Becker in 1835.
Practical and more successful electric road vehicles were invented by both American Thomas Davenport and Scotsmen Robert Davidson around 1842. Both inventors were the first to use non-rechargeable electric cells.
What advantages do EVs offer? EVs produce zero emissions at the point of use. An electric motor is 400% to 600% more efficient than an internal combus tion engine. An EV, per mile, uses one-half the fossil-fuel resources an ICE consumes. An EV produces only 5% to 10% of the emissions of an ICE per mile traveled. All of the EV’s emissions occur at a (oil- or coal-fueled) power plant, which runs 400% to 500% more efficiently than an ICE and scrubs its own exhaust. EVs can use electricity from anywhere including sustainable energy resources (wind and sun). EVs are simple, silent, and affordable to operate.
Zero-Emission or Emission-Elsewhere? It is a major step for an automobile to no longer emit exhaust gases. In fact, it is nearly inconceivable. That’s why consumers will love zero-emission vehicles. They may not be driving a solar-powered car, but they will be helping the sun to once more shine through clear skies.
In the literal sense, of course, the EV is the “emission-elsewhere” car. The electricity to power the car has to be generated somewhere. And, though some energy is available from sustainable energy sources like wind, solar, and water power, the bulk comes from coal- and oil-fueled power plants. Isn’t this just transplanting the problem somewhere else?
The answer is both yes and no. Yes, the pollution is transferred to another region. However, this matter has been scrutinized extensively by the U.S. Depart ment of Energy and several California agencies charged with air-quality manage ment. The bulleted list above reflects their findings.
EVs are very efficient. They have to be. A pound of battery has 1/100 of the energy of a pound of gasoline. On average, a 30 mpg ICE car uses only 5% to 10% of the energy of its fuel, whereas the EV converts 70% to 80% of the battery’s pack into propulsion, for the same mile.
Electric car operating costs can be directly compared to the equivalent operating costs of a gasoline-powered vehicle. A litre of gasoline contains about 8.9 kW·h of energy. To calculate the cost of the electrical equivalent of a liter of gasoline, multiply the utility cost per kW·h by 8.9. Because automotive internal combustion engines are only about 20% efficient, then at most 20% of the total energy in that liter of gasoline is ever put to use.

What is the most sustainable way to purchase soft drinks?
My family really enjoys soda pop, vitamin water, etc., but I see all of these plastic bottles and aluminum cans, and even though I take them to recycling, I know that a lot of energy and water are expended in making and recycling those containers. Any advice on how we can still enjoy soft drinks in a more sustainable way?
You can purchase from local company by supporting them
you can purchase value pack which mean instead of 24 pack, you can buy a 2L bottle instead in order to reduce waste.
Make sure you recycle all empty bottles and cans
make sure you purchase those ones that can be recycled.
