Your Questions About Sustainable Energy For All

Lisa asks…

What are some good jobs for recent non-science, liberal arts grads?

I’m very interested in sustainable energy, alternative energy, wind, solar, etc. I want to work somewhere exciting. I’d really like to own my own company but coming up with money to start is tough.

admin answers:

I just had to chime in after reading chuckles’ ridiculous, uninspired answer. Does she think that everyone running the company is a scientist? Of course not. They need salespeople, marketing people, SEO experts, and so on, just as most companies of all sorts have.

Let’s talk about salespeople. Most successful companies look at *everyone* as a salesperson. Forget the retail store salesperson stereotype. In the green industry, salespeople are *consultants* who solve problems for their customers.

You’ve picked the right industry. Obama will be focusing a large amount of gov’t resources in this sector.

I hope this helps you.

Linda asks…

Where can I buy a nice men’s hoodie that benefits an environmental cause?

I’ve been checking the sites of the Nature Conservancy, National Wildlife Fund, etc., and I can’t seem to turn up any nice-looking men’s hoodies. My boyfriend’s an environmentalist, so I’d like to get him something that would also benefit a cause he believes in, like helping nature or wildlife or sustainable energy, that sort of thing. Any ideas? There must be somewhere I’m not thinking of.

admin answers:

Why don’t you get him a donation to the Nature Conservancy or the National Wildlife Fund? You can skip the jacket all together and give the max to the environment.

Paul asks…

What’s the difference between Conventional, Conventional Alternatives, and Non-conventional energy alternative?

I’m doing some research and have trouble distinguishing the difference between these three types of energy sources.

So far, I have Conventional energy widely used/practical energy sources like oil, gas and coal. My assumption is that they’re the primary ‘standard’ energy sources the world currently uses for their electricity and power since the industrial revolution.

I’m having trouble with the next two energy sources..

Conventional Alternatives, I put that at energy sources that produce less environmental waste and could be used to replace conventional energy sources. An example would be biofuels being used to replace oil/gas for cars. I guess Nuclear power could go under this energy source as it could be used to replace coal in North America but places like France have 90% of their cities powered by Nuclear – would this mean it’s a conventional energy source for France and a conventional alternative to North America? I don’t know..

As for Non-conventional energy.. I put this at energy sources that produce the least amount of environmental waste but are completely unpractical to implement. My example would be hydrogen powered cars because there is no current infrastructure to support Hydrogen fuel gas stations if consumers were to buy them.

I’m just purely guessing here – please share if you disagree or agree with my definition. Also If anybody knows what category other energy sources like wind, solar, and thermal energy belong to, I’ll be super grateful.

admin answers:

Hey Fud, you have a bit of a mess there with definitions. Let me try to explain some of it. The term, “Conventional Energy,” is basically what you have written already. In most cases, it refers to fossil fuel based energies. You have to be careful with this, I’ll explain. Alternative Energy is any energy source that is used to replace a conventional energy source in order to offset the negative side effects of the conventional source. A simple example of this is switching from coal heat in an older home to natural gas. It is less polluting, more efficient, and costs less. Another example, however, was when coal became an alternative energy source for wood in industrial applications in the last century. So in a way, coal could fit into the category of alternative energy, depending on the context.

Your next one, “Conventional Alternative,” is not something I’ve ever heard thrown around in our circles here. It sounds like the news men who refer to airline pilots as, “Fully Qualified.” Most of the airlines I know do not have any partially qualified ones hanging around, but still that phrase shows up on the news a lot. My guess is that coal alternative I just mentioned might be one of those, a conventional fuel used in an alternative way, but I would just be guessing too. I think Non conventional would be the same as Alternative. Conventional Alternative sounds like Jumbo Shrimp to me.

The phrase you haven’t mentioned is the one that is most common in our circles here, “Renewable Energy.” This refers to any energy source that does not deplete with use, it, “renews itself,” over time, hence the name. Solar, wind, hydro and geothermal are the ones I am familiar with.

If you’re wondering where I’m getting all this, it’s because about 10 years ago we decided to convert our home over to wind and solar power. So our home would fit in the alternative category as well as the renewable category. People that grow their own tomatoes rather than buying them at the market know a great deal about soil ph, watering, sunlight and fertilizer, they have to. People that grow their own electrons instead of buying them from the power company have a similar curse, they want to know where each one comes from and where it’s used. So in the end, you learn a bunch of stuff that you can’t really use anyplace else.

I suspect if you’ve been reading these things in popular periodicals like Popular Science, Home and Garden, or the newspaper, you’re just getting caught up in their vernacular on the subject. If you want to go to the source, I will include some places below you can look for more information. Hope this helps. Good luck, and take care.

Your Questions About Sustainable Energy Companies

Donna asks…

how to look ahead to a sustainable future?

What is going on with a sustainable future? What are the problems associated with this and what can be done to solve it? What are real world examples?

admin answers:

Basically a sustainable future would be one in which the majority of resources and energy sources we utilize are renewable, coupled with disposing wisely of waste (and reducing the amount of waste made in the first place), managing land responsibly and eliminating air, water and soil pollution. Renewable forms of energy include bio-fuel, solar, wind, hydro, and some would argue things like methane harvesting, hydrogen, and nuclear. This would include phasing out and ultimately getting rid of fossil fuels, which all pollute when “burned” to make energy (admittedly some far less than others) and are finite (i.e. Not renewable; once they are gone, they are gone). The mining/drilling to harvest them has a significant environmental impact as well. Renewable resources would include plant based plastic products & fabrics, fast-growing tree varieties that don’t deplete the soil, utilizing materials that can easily and cheaply be recycled again and again, etc. Better waste management also goes back to recycling and reusing (for instance millions of items are thrown out every year that could be donated to thrift stores, homeless shelters, etc) but also reducing the amount of unnecessary waste by producing products that are more durable, with less packaging that can be recycled when they are no longer able to be repaired.
Problems with achieving more sustainability include the following:
1.Resistance to phasing out fossil fuels – many of the economic and political powers of our time are involved with the fossil fuel industries in some way and are afraid of losing their fortunes. They fight to keep regulations weak and ultimately to work against renewable energy sources being researched, refined and widely implemented. The average American also does not want to pay more for alternative fuel or for a vehicle that will use it, even if the long term savings make up for (increased mpg, longevity, etc). Thus there is not a push on the government or large corporations to research alternative energy or improve mass transit (as it is in Europe).
2.Poor land management – for instance reducing meat consumption would reduce the needed amount of farm animals, reducing the demand on the grain supply. The grain we feed animals for meat would feed thousands of times more people than it does animals. We also need to think about WHAT we plant for renewable resources – for instance using all corn for ethanol and bio-fuels has jacked up the price of corn for countries that use it for food and has severely decreased bio-diversity (having a wide variety of crops), which is very bad for the soil. It has other economic factors as well. We also have to consider the way we farm – are we polluting the soil and rivers with runoff?
3.Laziness and apathy – People don’t want to do anything that takes extra time, money or effort; they don’t want to recycle, read labels, lobby companies and politicians for greener products and policies, pay a little more for organic or for an electric vehicle, etc. People believe the convenient lies some people weave about global warming being a face and pollution not being a “big deal” (or the often heard idea “I’ll be dead when it’s really bad so it doesn’t matter” or “one person can’t make a difference”) because then they don’t feel bad about themselves or their choices.
4.Lack of government initiative to “green” the country, even on a local level – many municipalities, and the state and federal governments as a whole, don’t put the effort into promoting green policies, renewable energy and conservation necessary to fuel real change. In the same way many Americans did not want racial equality but the government passed the Civil Right Act to force it, the government needs to step in and legislate green concerns. The conservative body always decries the government being involved in people’s lives, but frankly many people are selfish and uninformed and won’t “do the right thing” unless forced. We can’t sit back and do nothing about a huge problem just people don’t want to be told what to do like spoiled teenagers. Because the government doesn’t push harder regulations, or offer better incentives, the corporate sector is not willing to invest in utilizing or developing green technology, keeping it expensive and not easily accessible.

James asks…

How could world energy consumption be more evenly distributed?

I know that my family uses alot of extra energy and I think its safe to assume other American families also consume more energy than neccessary. But how exactly will me turning off the lights when I leave give third world countries energy. Also alot of developing countries lack clean water because purifying water requires energy some parts of the world just don’t have, should more developed countries step in, if so how?

admin answers:

>How could world energy consumption be more evenly distributed?

Make the poor areas more prosperous! Stop thinking of energy consumption as a driver, it is a consequence.

>But how exactly will me turning off the lights when I leave give third world countries energy

It would have almost zero effect. But what about if everyone used 10% less power and sent the money that would have gone to the power company to some organization working on providing clean drinking water to third world countries?

>should more developed countries step in, if so how?

They have! Particularly the US has spent a lot of money over a long period of time. With very little to show for it.

The problem is it is extremely difficult to “give” prosperity to someone in the long run. This is true of both individuals and countries. This seems to be human nature.

The key seems to be changing the culture/mindset of the recipients to make improvements sustainable. But doing so is not only difficult, it’s politically incorrect.

Your Questions About Renewable Energy World

Sandra asks…

How much money was made from renewable energy 2011?

I’m trying to see how much money was made from renewable energy sources such as solar and wind.

admin answers:

Thats a good question. Perhaps not as much was made as was spent developing those sources. Renewable energy has been a prevailing issue due to our energy dependence and the high cost of oil. While the high cost of oil makes huge amounts of money for oil companies and OPEC, we will undoubtedly one day have to resort to the use of alternative and renewable energy to power our vehicles along with other modes of transportation as well as heat our homes and generate electricity for households and businesses. My speculation is that we will continue to use light sweet crude until the wells in the middle east run dry and then develop corn ethanol and become the primary exporter of fuel in the world bwahahahaha

Thanks , i need the answer+explaination by tonight .

admin answers:

Geothermal As A Green Energy Source
——————————————————————————————————————————————-

Geothermal energy is energy obtained by tapping heat from the earth itself. This comes from magma and the radioactive decay of uranium, thorium, and potassium.

The downside to geothermal energy is the fact that it is expensive to build. On the other hand, because the earth’s crust continuously decays replenishing the heat, it is still a renewable source of energy.

There are three types of geothermal plants around. These are namely dry steam, flash, and binary.

Dry steam plants take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator.

Flash plants take on water at temperatures over 200 °C, out of the ground, and allows it to boil as it rises to the surface then separates the steam phase in steam/water separators which runs the steam through a turbine to generate electricity.

Last, you have binary plants. Here, hot water flows through heat exchangers and that boiling organic fluid is what spins the turbine.

Once power is generated, the condensed steam and remaining geothermal fluid from all three types of plants are injected back into the hot rock to pick up more heat.

Geothermal plants are used operational in different parts of the globe. These are usually located in geologically unstable parts of the planet. You can see some in Chile, Iceland, New Zealand, United States, the Philippines and Italy. At home, two most prominent areas for this are in the Yellowstone basin and in northern California.

If you were to compare the amount of energy collected from geothermal to solar, you still get more from the sun. Despite that, people should still use it since solar energy cannot be harnessed when the clouds block the sun’s rays from reaching the solar panels.

Geothermal energy is a green energy source just like wind, hydropower and biofuel because it is a renewable. By maximizing its potential, we don’t have to worry about the price of oil in the world market when it hit more than $110 a barrel and is now under $40 in the world market.

But that is not the only thing we should be concerned about. We should also do our best to protect the environment given that coal fired and nuclear power plants produce harmful gases and radioactive waste that may cause to people and the surrounding areas.

———————————————————————————————————————————————–

Why Is Hydropower A Green Energy Source?

Why is hydropower a green energy source? It is because we are able to harness electrical power by converting water into electricity.

The use of hydroelectric power or even hydroelectricity dates back to Ancient Greece and China when they installed waterwheels in rapidly flowing rivers to turn millstones and other equipment. Years later, this was used in the New World which is now known as North America to power saws and other equipment.

But the hydroelectric plants of today still use the same basic principles as the historical waterwheel with some variations. The difference is that we use the force of the power to push the turbine which in turn powers a generator thus generating electricity.

To make sure that there is a steady flow of power being produced, a dam has to be built to retain the water. If there is a need for more power, the gates of the dam are opened so water can be released. During non-peak, the gates are closed. To ensure there is water at all times, some dams have a recovery and pumping systems to the water released can be used again.

There are issues with the use of hydroelectricity. Some claim that it poses a problem for fish and aquatic plants on both sides of the dam. Because the flow of water has been altered, the nutrient rich silt which helps crops grow could be affected which is exactly what happened when the Aswan Dam was completed in Egypt.

Lastly, you have ocean thermal energy. Here, you get power based on the different temperatures in the water. For this to work, you need at least 38 degrees Fahrenheit difference between the warmer surface water and the colder deep ocean water. Still in the trial stage, it is used Japan and Hawaii.

Hydropower is a green energy source. It is safe to use and what is even better is that it is renewable.
