The document summarizes a feasibility study conducted by the US Army Corps of Engineers to develop renewable energy at a military training complex in Afghanistan. It assessed various renewable technologies including wind turbines, solar PV, solar hot water, and lighting retrofits. Due to logistical and maintenance challenges, larger wind turbines and solar arrays were deemed too difficult and smaller, distributed systems were recommended instead. Contractors in Kabul could install and maintain the proposed smaller systems. The study also considered energy efficiency upgrades and conducted site assessments to identify the best locations for wind turbines.

ABSTRACT
In India, more than 200 million people live in rural areas without access to grid-connected power. A convenient & cost-effective solution would be hybrid power systems which can reduce dependency on grid supply, improve reliability. For a typical domestic load a solar –wind hybrid system is designed with charge controller to charge a conventional battery. To optimize system efficiency, a simple algorithm is developed for system sizing. Total cost of unit is calculated using life cycle cost analysis and payback period.

Today, the world is progressing at quite a fast rate with the use of the conventional sources of energy. The two major demerits of using them are the environmental pollution created by its use and its limited quantity.
On the other hand the Non-conventional sources of energy are available in plenty, free of cost and pollution free.
Many types of clean and renewable energy sources can be used in the production of electrical energy.
The most vital way to take care of our lives is to take the responsibility of our own energy foot print.
Renewable energy plays an important role in the supply of energy. When renewable energy sources are used, the demand for fossil fuels is reduced. Unlike fossil fuels, non-biomass renewable sources of energy (photovoltaics, wind, hydropower, and geothermal) do not directly emit greenhouse gases.
Renewable energy is energy generated from natural resources such as : sunlight, wind, tides, and geothermal heat which are renewable (naturally replenished).
The use of renewable energy is not new. More than 150 years ago wood, which is one form of biomass, supplied up to 90 percent of the energy needs. e.
Now over half of renewable energy goes to producing electricity.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Information collected after feasibility study
The 3 X cost multiplier does not capture in sufficient detail the site conditions
• Logistical difficulties:
• 1 MW turbine requires a 300 ton crane
• Largest section to move by truck is 35m long
• Multiple contractors around Kabul verify that the
largest crane available is 125 tons.
• Theft and vandalism are issues.
• Lack of technical capacity available for
operation and maintenance.
• USAID failures in micro-hydro caused them to
recommend: “In the short-term, make every effort
to slow developments to match the capacity by
downsizing planned government and donor
programs … to accommodate sustainable
development.”
• Rough terrain, insufficient

Results From In-Brief with the Senior Science
Advisor (SSA) to the Commander
GO-AHEAD GIVEN TO:
• Reduce the size and increase
the number of wind turbines.
Five 10-12 kW units tentatively
approved; potential for more.
• Install 50 kW PV in multiple small
systems.
• Consider efficiency and low-tech
RE for RFP.
• Cancel complex WTE plant.
• Cancel complex anaerobic
digester.
EMPHASIS ON:
• Social value: demonstrating that
RE can work here, showing the
public that we’re trying things
that work.
• Five-year paybacks are preferred
• Waste and waste-water sludge
both still require trucking off the
installation, which presents a
security issue. If possible, SSA
would still like recommendations
on these items.

Wind Power
Installing a 1MW wind turbine is impossible at worst, risky at best
The limitations mentioned above
make a 1 MW turbine risky at best.
Even if it could be installed and
maintained, it is an unrealistically
large investment for a site with no
detailed wind study.
Furthermore, multiple small
resources increases resiliency in a
difficult maintenance environment;
failed turbines represent a smaller
percentage of the overall capacity,
and can be cannibalized for parts if
necessary.

• The current hot water scheme is many electric
resistance tanks in every building.
• The assessment identified buildings with heaters
in the same general location, making
supplementing with solar hot water more feasible.
• Diesel boilers also have the potential to reduce
diesel consumption per Btu of hot water by a
factor of 3 or 4. Propane is also an option, as it will
be supplied to the DFACs for cooking.

Solar Hot Water
Comparing a low-solar-fraction electric backup SHW system to a ordinary

A low solar fraction
with electric backup
can consume more
diesel than a simple
diesel boiler.
The “break-even” solar
fraction when
comparing these two
systems, is 69%.

and a diesel boiler efficiency of 80%)
21
22. BUILDING STRONG®
Solar Hot Water
Four options
• Use a high solar fraction solar system (>80%)
with the existing electric water heaters as
backup.
• Accept the added complexity of SHW with a
diesel or propane backup.
• Implement diesel or propane boiler alone.
• Heat pump water heaters with or without solar
backup (this option likely unavailable)

23. BUILDING STRONG®
Lighting Retrofit
The lighting load can be cut in half in most places.
Magnetic ballasts were used in Phase I because electronic ballasts are
difficult to get in Kabul. ANSU is large enough to justify importing a large
order from Dubai, however, and the high reliability of programmable start
electronic ballasts suggests that 10-15% spares should be adequate for
the foreseeable future.

The spaces are also over-lit. 6500K lamps are more common in Afghanistan than
in the US, and the light they provide is used more efficiently by the human eye.
The US-based designers might not have taken this into account when designing
the lighting; one lamp-fixtures in most locations would give adequate lighting.
Replacing with one-lamp fixtures with electronic ballasts will have a (roughly
estimated) 4.4 year payback.

Reflective roofs have the potential to increase comfort in most buildings and
reduce cooling energy in the air conditioned buildings.
