What are the hurdles for big industries to have their own wind/solar energy plants to meet their requirements?

Posted on August 2, 2011 by admin


Just as the other two have already stated, space is a big issue. Also, batteries. Wind & solar energy are not available everywhere in the US and around the world. It can only be very effective in certain areas (like the Southwest for solar and Midwest and Appalachian Mountain Chain for wind). There currently is not an efficient way to store and transport energy to other parts of the nation/world.

So, in addition to what everyone else has said so far, I would say that the industry’s biggest hurdle is focusing primarily on wind and solar. They should be looking at biomass, hydrokynetic, and other forms, as well. Did you know cow manure (a form of biomass) can be processed to use the methane as a source of energy (like natural gas… It is natural, and it is a gas). The by-product of the process is smelly-free fertilizer! Farmers that have used the method on their dairy farms are churning out so much electricity into the grid, their entire farms run on it AND they get money from the power companies that service their area.
Hydrokynetic is relatively new to the industry. Basically, it’s the equivalent of putting huge turbines under large bodies of water to use the energy of the currents to create electricity.

If there are solar energy panels, is there anything to save water?

Posted on July 29, 2011 by admin

I know there are solar energy panels and wind turbines but is there anything for water? Also, how much money would you save a year if you installed a solar panel and wind turbine? No rude comments.

to save water .here r some methods
Water-saving technology for the home includes:
Low-flow shower heads sometimes called energy-efficient shower heads as they also use less energy,
Low-flush toilets and composting toilets. These have a dramatic impact in the developed world, as conventional Western toilets use large volumes of water.
Dual flush toilets created by Caroma includes two buttons or handles to flush different levels of water. Dual flush toilets use up to 67% less water than conventional toilets.
Saline water (sea water) or rain water can be used for flushing toilets.
Faucet aerators, which break water flow into fine droplets to maintain "wetting effectiveness" while using less water. An additional benefit is that they reduce splashing while washing hands and dishes.
Wastewater reuse or recycling systems, allowing: Reuse of graywater for flushing toilets or watering gardens
Recycling of wastewater through purification at a water treatment plant. See also Wastewater – Reuse

Rainwater harvesting
High-efficiency clothes washers
Weather-based irrigation controllers
Garden hose nozzles that shut off water when it is not being used, instead of letting a hose run.
using low flow taps in wash basins
Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands.
A valve which reduces water, gas, time, money and CO2 known as a Combisave

Water can also be conserved by landscaping with native plants and by changing behavior, such as shortening showers and not running the faucet while brushing teeth.

What technology and chemical serves the same function as chloroplast, other than solar panels?

Posted on July 25, 2011 by admin

What technology and chemical serves the same function as chloroplast, other than solar panels? Solar panel converts solar energy in to electrical energy and the chloroplast of a plant cell converts solar energy in to chemical energy. Is there any other technology and chemical that converts solar energy in to any other type of energy ?

solar heaters to convert sunlight to heat

What role does information technology play in the solar energy industry? and how is IT used in this industry?

Posted on July 20, 2011 by admin

Appreciate any information the areas in the solar energy production or solar cell manufacturing where IT plays a role? IT firms providing solutions or technology to solar companies or case studies?

Thanks.

Any manufacturing is going to need control of inventory, process control, and procurement of materials at best prices.

Large solar facilities will need to track the output of each panel and each inverter individually, or at least track groups of them, so that if something breaks, the company can go and fix it. They can also notice a slight percentage drop in output, possibly indicating that the panels need to be cleaned.

Selling the electricity is a financial transaction. The kind of bidding and selling that Enron did still goes on, but is more regulated now. As such, it’s the similar to a stock market, and lots of IT is needed.

How much energy in joules can the solar panel produce each day?

Posted on July 16, 2011 by admin

Suppose one square meter panel of solar cells has an efficiency of 30% and receives the equivalent of 4 hours of direct sunlight per day. How much energy in joules can it produce each day? What average power of watts does the panel produce? If the solar cells were efficient they would generate about 1000 watts of power per square meter of surface area when exposed to direct sunlight.

4 hours = 14400 seconds

1000 watts of power per square meter

1000 watts = 1000 joules per second
1000 joules per second x 14400 seconds = 14400000 joules
30 % of that = 4320 000 joules.

since this is joules per day per m², the answer is 4320 000 joules/meter/day
or 4.32 MJ/m/day

Which is a better way to use solar energy, mass-production or individual home usage?

Posted on July 1, 2011 by admin

I know we need to put a ton of effort towards research in renewable energy, specifically solar. But when it actually becomes a viable alternative to oil, and we can ~store~ solar energy efficiently, would it be best put to use atop individual homes and buildings, or as a source of electricity for whole cities?

The biggest problem you have with large solar installations is finding a large area near a major population center. In many cases the town councils love the IDEA of solar energy BUT just don’t want the solar energy farm IN THEIR TOWN!

In terms of efficiency, a large solar installation is far more efficient than solar panels on everybody’s roof.

However in this case the Political decision ends up trumping the Engineering decision.

Can some one translate this please? and is this translation correct?!?! in french please!! natvie speaker!?

hey i want to say this

In our modern society we have the potential to use all different means of energy. In Australia it is a perfect country to use solar power! I personally do not know why it is taking so long for the governments to implement this. I would also recommend that you look into nuclear energy as an alternate means of power to supply the nation.

Even though nuclear energy is more efficient than the current usage of fossil fuels, we cannot debate that solar energy is the way to go. Even on a rainy day you will still produce more energy than you will consume. But honestly why not be self-sufficient? It saves your money and it saves the environment!

how i have translated it.
Dans notre société moderne, nous avons la possibilité d’utiliser tous les moyens d’énergie différentes. En Australie, il est un pays idéal pour utiliser l’énergie solaire! Personnellement, je ne sais pas pourquoi cela prend si longtemps pour les gouvernements à mettre en œuvre. Je recommande également que vous regardez dans l’énergie nucléaire comme un moyen alternatif d’électricité pour alimenter la nation.

Même si l’énergie nucléaire est plus efficace que l’utilisation actuelle de combustibles fossiles, nous ne pouvons débattre que l’énergie solaire est la voie à suivre. Même par une journée pluvieuse vous serez toujours produire plus d’énergie que vous consommez. Mais honnêtement pourquoi ne pas être auto-suffisant? Il économise votre argent et il sauve l’environnement!

please help =P thanks!!

Not bad . I had to change some expressions, grammar structures such as subjunctives and some words .

What is the future of solar energy’s technology?

Posted on June 26, 2011 by admin

I’ve been thinking about spending over $30,000.00 on solar panels for my house for a while because our electric bill is often $300.00 per month. But a construction worker who is friends with someone in the solar energy business strongly advised me to wait. He said that although the solar energy business has been around for 30 years, its technology is still in it’s infancy.

But because of increasing popularity, it is expected to become doubly as effective and cost A LOT less (if not half as much). But there are huge government rebates right now that will lower the price and I don’t know how long it will be until the technology advances come around.

My construction friend is suggesting that buying a solar panel today would be like buying a flat screen television when it first came out. They cost over $5,000 when they first came out. Now you could buy an ever better set than the one you bought only a few years ago for less than $1,000.

Does anybody out there have any inside information on the future of solar energy technology?

I don’t have any inside information, but that is the way technology works. Solar panels are not very efficient at this point and are quite taxing on the environment with their production. If you figure 5% interest, Just the interest will cost you $1500 pr year. That leaves $2100 per year to pay off the initial investment. It will take almost 15 years to pay off the investment. I don’t think they are cost effective at this time.
