Renewable Energy

Currently, the largest wind turbines in operation have rotor diameters of around 220 meters, such as the GE Haliade-X. The size of wind turbines is limited by logistical constraints such as transportation of equipment and the ability to withstand extreme weather conditions. Additionally, as turbine size increases, there are diminishing returns in terms of energy production and cost efficiency.

Entropy always increases :(.

One way of looking at it is all energy wants to be waste heat, and all life and machinery is a system of toll bridges, extracting useful work from the energy on the way to it's final destination.

Once the energy arives, it has no desire to go anywhere so toll bridges don't turn a profit.

You would likely move faster down a waterside due to the reduced friction from the water acting as a lubricant between your body and the slide surface, compared to a regular slide where friction between your body and the slide surface slows you down.

A non-renewable energy source is a natural resource that cannot be replenished at a rate equal to its consumption. Examples include fossil fuels like coal, oil, and natural gas, as well as nuclear energy sources. Once these resources are depleted, they cannot be easily replaced.

A page author affiliated with a governmental agency, a reputable research institution, or an environmental organization is more likely to be an unbiased source of information about renewable energy. Look for authors who cite reputable sources and provide balanced perspectives on the topic.

Fossil Fuels. The sun, wind and heat from the earth core is continuously being produced. Fossil Fuels were created over a long period of time and required a lot of heat and pressure to be created which is why they are not considered to be renewable.

Some forms of wave energy, such as x-rays and gamma, can penetrate human skin and kill cells within the body (this is why they are used to treat cancer). However too much exposer can be extremely harmful causing bodily defects and can alter the way unborn babies develope.

One that doesn't work cheaply or well enough to be a prime energy source.

No, that's not the answer your teacher is looking for... this is approved "green" answer what they want from you:

Alternative energy sources are those which are renewable, not based on the consumption of a fixed resource like coal, uranium, or petroleum.

Alternatives are clean and safe, with low environmental impact, unlike dirty coal and dangerous nuclear power.

But don't tell your teacher that wind turbines kill birds and bats by the ton, that tidal power destroys fish, that geothermal power creates earthquakes, or that most solar panels have dangerous heavy metals in them.

That's not the indoctrination they are after.

Resource availability refers to the presence and accessibility of resources needed to complete a task or project. It involves having the necessary tools, materials, information, and personnel readily available for use in a timely manner. Monitoring resource availability is important to ensure that projects can be effectively executed without delays due to shortages or constraints.

I think this is easy to answer. If there is no renewable energy available, all out non renewable energy will run out. The continuous gas price hike is one indication of fossil fuel depletion. If we ran out of fossil fuels, electricity would really be expensive as we have to find other sources. Basically, all machines, equipment or anything that needs fuel to run, will have to run from another source of energy.

Okay, so renewable energy is basically energy that can be used again, and is an endless resource; the opposite to things like coal which are burnt- full stop.

Solar panels can transform sunlight (renewable energy) into electricity, wind turbines can transform wind power into electricity and dams can do the same with hydraulic power I think. Electricity can be turned into heat in turn, or heat can be found directly from the sun, a renewable energy source.

I hope this helps!

The State of The County Address was given by the Board of Supervisors Chairman Ray Castillo on Thursday February 21. The theme was "The Dawn of Our Renewable Era"

After years of talks, protest, lawsuits, and planning the renewable energy industry is finally making an impact in the Imperial Valley. With 6 projects in the construction faze, creating over 2000 construction jobs that will lead to over 100 permanent jobs. The Renewable Energy Industry was a focus of Chairman Castillo's address.

Other topics where about some of the challenges that hit the Valley in 2012, the flooding in Calipatria and the earthquake swarm that hit Brawley. Castillo stated "Agencies stepped in and quickly assessed the situation, made the necessary repairs and rendered assistance."

The Imperial Valley also saw the rehabilitation of nearly 17 miles of pavement in Niland and Seeley and the completion of the Brawley Bypass, a $235 million project.

Castillo also commented on Air Pollution Control and how the County has made great strides to meet the Clean Air Act and avoiding sanctions and lawsuits. Castillo also said, "It seems we may be making some progress in addressing some of the vexing issues facing us at the Salton Sea," by seeking settling disputes with the Imperial Irrigation District and supporting legislation crafted to alleviate "this long-troubled body of water."

"The Imperial County Board of Supervisors, along with the (Imperial Irrigation District) Board of Directors, expressed the common goal of having Imperial County become the renewable energy center capital of the world," he said, "and I for one am proud, as I think we all should be of seeing that dream become a reality."

Solar energy is energy produced by the sun's nuclear reactions. Solar energy can be harnessed through solar panels to generate electricity or used for heating applications. It is a renewable and sustainable source of energy.

Natural Resources are things that were made by nature. man made is something someone made such as Desks Toys Plates etc... Natural resources are trees plants coal oil gas. No one made them.

It depends what you mean by "renewable". Radioactive materials do not "grow" the way trees grow. There are naturally-occurring radioactive elements. Elements can also be made radioactive by various means that involve atomic collisions, and this may occur in nature or as a result of human direction.

It is true that the majority of the fuel used in a reactor eventually becomes "spent". That is, it gets to a point where it stops producing useful power. It is still, however, radioactive. Spent nuclear fuel can be recycled and reused in some cases, depending on the isotope and the form of the fuel. We will probably become more successful in recycling spent fuel as our technology advances.

There is no reason to suppose that nuclear fuel could not be effectively infinite, particularly as compared to resources like petroleum and coal. The amount of nuclear fuel require to produce an equivalent amount of electricity to other energy sources is a very small fraction. It is extremely efficient in terms of energy yield per kilogram of raw material.

I worked at a nuclear power station for a little over a year in the eighties, and the short answer is that the heat from the reaction is used to generate steam which then turns a very large turbine to generate electricity.

But that answer has become outdated. The nuclear energy is what powers the turbines which generate the electricity.

The term renewable energy refer to timely balance of energy collection and consumption.

Fossil fuel took around 1 million of year to form but about 200-300 year of use till deplete thus it could not be regenerate within our civilization time frame. In other hand, if we use energy from biomass or solar cell, we collect energy, store and use at the same pace and it will not be depleting at any few million year from now. Since the collection of energy is at pace with consumption then it is considered renewable resource.

_________________________________________________

Because renewable energy resources are not depelatable in the sense that they are replenished in less than 100 years.

Technically speaking, the molecular movement of water and how fast the molecules vibrate, the energy of that can be captured and the form of energy can be used to generate electricity. They use the hoover dam to do that.

There are previously depleted oil deposits which have been discovered to be refilling. This has caused speculation that the Earth makes the stuff.

I've often wondered: If crude oil is the product of decaying life, how did so much of it get so deep below the surface?

the "disappearance" of a small amount of mass

Most people figure that there will always be some more wind coming along later, so they call it renewable.
It will never be depleated. ex. fossil fuels are non renewable because eventually they will run out. Wind will always be around for our use.

A tungsten bulb is a common lightbulb, the fillamint in a bulb is the small wire in the middle that's drawn across the two contacts. This wire provides an electrical resistance and heats up and this generates light.

In a common lightbulb all the air must be taken out and replaced with an inert gas to stop the tungsten fillament burning away.

It is not economical compared with other sources of energy.

First of all molecular hydrogen (H2) only exists on earth in small quantities, so

you have to make it from other sources. Most generally this would be made from natural gas (mostly CH4). But 'burning' natural gas to make hydrogen for fuel doesn't make any sense, as the energy density (per volume at standard temperature and pressure) of natural gas is better than hydrogen so why not

just use natural gas in your device in the first place?
