Your Questions About Renewable Energy Definition

Robert asks…

What are some difficulties in achieving sustainable development?

Definition: Sustainable development is a pattern of economic growth in which resource use aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come.

Why is it difficult for humans to achieve sustainable development?

And why?

admin answers:

You clearly haven’t bothered thinking about this at all:

– we don’t recycle 100% of all metals, so any metals you use will not be available for future generations to use. So, by your own definition, you can’t use any metals.

– once coal, oil, or natural gas is burned, it can’t be recycled, so any coal, oil, or natural gas you use to make anything, to transport what you make, or to transport the materials will not be available for future generations. So, by your own definition, you can’t use energy that comes from coal, oil, or natural gas.

You can argue that energy comes from the sun, from wind, or from water is O.K., but you still have to build the power plants to use those energy sources and that isn’t O.K.

Etc.

– there are resources that are theoretically renewable, but we are already cutting down trees faster than they grow back, so wood, lumber, etc. May be theoretically sustainable, but in practice, using them is not sustainable.

The bottom line is that we have too many people using any and all resources at far too great a rate to be sustainable, so anything additional you do is by your own definition, not sustainable.

Now you can cheat in many ways: change the definition of sustainable so that it becomes feasible; pretend that advancing technology means that in the future people will be able to do anything with whatever they happen to have left over (isn’t magic wonderful?) so it doesn’t matter what we leave for future generations; etc. Or you can admit that sustainable development is an oxymoron and work toward other goals.

Sandy asks…

What is the definition of Visual Pollution and give some examples on how to prevent it…..?

I’ve been looking for a definition of this for hours!

thank you.

admin answers:

As the saying goes, “beauty is in the eye of the beholder.” Visual pollution is going to have different meanings to different people. Most people would agree that excessive billboards are unattractive, but some may see skyscrapers as ‘visual pollution’ (spoiling the once natural landscape), while others may love viewing their architecture. Wind Farms (large areas covered by many wind mills) would be another example of visual pollution to most people. But then we are faced with the question ‘is it worth it for the renewable energy?’

How to prevent it? Stop building. But that’s just my opinion; some people may not like the looks of trees and fields and prefer building and signs.

Here’s some info. From Wiki:

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.

James asks…

I need to no what conventional and alternative energy is?

I have this huge geography test tomorrow and i was away alot of the time for this class so i didnt get any of the notes i need so i need to no everything possiable about the following :
conventional energy
alternative energy
sustainabilty
hydrogen
energy
water

Anything will help!

Thanks!

admin answers:

I’ll give you one to get you started.

Alternative energy is energy derived from sources that do not harm the environment or deplete the Earth’s natural resources. Typical sources include wind and solar. Nuclear power is usually excluded from this definition.

Linda asks…

Is tidal Power tiddle power compared to the power of the Nukes Industry?

Slim Footwear (Greenpeace) responding to Chris Hulme’s announcement that 8 Nuclear Power Stations are to be built and the Green Energy tidal generation plans will be scrapped.
“Lib Dem voters backed a party that supported renewable energy and opposed taxpayer handouts to the nuclear industry..”

admin answers:

It depends largely on how you cost the two proposals. If you ignore the cost of decomissioning and waste treatment, then nuclear power is more economical.

If however, you factor in the cost of decomissioning and treatment of waste – the case for nuclear power becomes very, very difficult to support. That’s just the financial cost – there’s also human costs as regards unwanted land use.

Tidal power – by definition – does not take up any land, other than to manufacture the equipment.

This is very disappointing.

Paul asks…

What is the difference between renewable and sustainable energy sources?

Can something be sustainable but not renewable?

admin answers:

Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides, and geothermal heat—which are renewable (naturally replenished)Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

Each of these sources has unique characteristics which influence how and where they are used.

Sustainable energy sources are most often regarded as including all renewable sources, such as biofuels, solar power, wind power, wave power, geothermal power and tidal power. It usually also includes technologies that improve energy efficiency

Carol asks…

Do the leftwingers like sticking a giant middle finger in those who sacrificed to make our lives better?

Dinosaurs sacrificed their bodies to become our fuel, but liberals don’t want to use fossil fuels. That’s right; dinosaurs, which are one of the definitions of AWESOME in the dictionary, are being told to go away by the liberals.

Using renewable energy is the same thing as saying “**** YOU!” to the dinosaurs. FACT.

admin answers:

That fossil fuel is also responsible for polluting this world. We accept that we’re still dependent on fossil fuel, but we are also exploring non-polluting energy resources.

Jenny asks…

What real experience (not self serving or self promoting) is Hillary Clinton talking about?

Clinton as made the statement “since when has experience become bad?”
What experience does she have? If she were not married to Bill Clinton, is there anything she has done that would associate her name with: women’s rights? Health care? Children’s advocacy? Homeland security? Renewable energy?

Other than taking donations in exchange political favors that usually means the working class will be paying for it, what has she actually done in ther alleged career?

admin answers:

In a news conference Deanna Favre announced she will be the starting QB for the Packers this coming Sunday. Deanna asserts that she is qualified to be starting QB because she has spent the past 16 years married to Brett while he played QB for the Packers. During this period of time she became familiar with the definition of a corner blitz, and is now
completely comfortable with other terminology of the Packers offense. A survey of Packers fans shows that 50% of those polled supported the move.
Does this sounds idiotic and unbelievable to you? Well, Hillary Clinton makes the same claims as to why she is qual ified to be President and 50% of democrats polled agreed. She has never run a City, County, or State.

When told Hillary Clinton has experience because she has 8-years in the White House, Dick Morris stated, ‘So has the pastry chef.’

Sandra asks…

Definitions of non-renewable and renewable energy sources?

I need good definitions for both

non-renewable energy source

and renewable energy source.

admin answers:

Non-renewable uses a source that consumes a natural resource in limited supply. (Oil, coal… We can’t make more so it depletes the existing supply.)

Renewable uses a source that can be taken or grown and therefore can be replenished (Sunlight, wood, corn… We can make or take more and it doesn’t deplete a limited supply.)

David asks…

What would happen if we didn’t use renewable energy?

What do scientists fear if people didn’t use renewable energy?

admin answers:

By definition, non renewable energy can’t be renewed. It is finite and it will run out. We don’t have an accurate measure of how much fossil fuels we have left or how long that supply will last us. Many scientists believe we have passed the 1/2 way mark and we will see shortages in less than 25 years maybe sooner if we don’t learn to conserve what we have.

Renewable energy isn’t just about saving the environment, although most of them are much cleaner and produce far less pollution than fossil fuels. Renewable energy is also about ensuring our quality of life and for many it’s about energy independence.

I have solar panels which produce most of my electricity, when the city raised our rates by 20% it made little difference on my bill, if I hadn’t installed my solar system it would have been an additional $50 per month.
