The document discusses energy conservation in India. It notes that while India has 5% of the world's population, it accounts for 26% of global energy use. Improving energy efficiency through technologies like compact fluorescent light bulbs, solar water heating, better insulation, and higher efficiency appliances can significantly reduce energy costs for Indian households while cutting carbon emissions. Energy conservation has already saved India an estimated $12 billion per year in avoided electricity costs compared to continuing higher usage trends, but further opportunities remain in buildings, transportation, and industry.
Solar Power vs Wind Power for Individuals - Henrik FrankHenrik Frank
Is it a better solution for “carbon neutral” homes to utilize on-site solar or wind power or should these be provided in commercial scale farms.
By Henrik Frank
2008 Presentation I gave at Grinnell college arguing for renewables and efficiency to replace coal for electrical generation
I give concrete plans for how to transition to renewables for small Iowa communities and do it at a profit
ACHIEVE NET ZERO CO2 BY 2050 or an Economic Depression
ECONOMICS (GDP)
- Increasing climate extremes cost $390 billion in 2020.
- Present trends indicate a 10%-GDP-decrease depression
-Carbon Fee Plus Dividend solution
NON-CARBON EMITTING TECHNOLOGIES:
Electric Vehicles (EVs) charged by
Next generation nuclear reactors
Electricity is the life blood of Economic development of any country. The success of any country is only possible with the availability of it. The people of Afghanistan desperately need it for their socio economic development. All major polls show that Afghans wants electricity more than anything else.
The decades of war have left the country's infrastructure unfortunately spifflicated as well as the power grid badly damaged so it becomes more difficult to get electricity out there fast by using conventional cheap electricity generation methods.
The provision of renewable energy power plants to Afghan villages is a feasible speedy solution which can provide the electricity in few days with no fuel cost. Sustainable energy can be provided and the dream comes true.
Energy can be provided by the burning fossil fuel but the main drawback associated with it is the unfortunate security issues in the country. So for time being production of energy from renewable such as solar, wind, bio gas seems only the feasible solution.
Firstly, an on grid provision of electricity may be established for Afghans further it may be extended to off grid solution with step by step installation at selected vicinity on the basis of good maintenance of current grid system.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
2. Why India ?
With 5% of the world’s population, the India 26% of
the world’s energy.
A India resident consumes 12,000 kWh of electricity
a year, nine times the world’s avg.
The average indian household emits 23,000 pounds
of CO2 annually.
Two billion people in the world do not have
electricity.
Just using off the shelf technology we could cut the
cost of heating, cooling, and lighting our homes and
workplaces by up to 80%.

7. Conservation Economic
Savings
If India electricity use had kept growing at the
US rate, kWh/person would have been 50%
higher
India electric bill in 2004 ~$32 Billion…
so we’ve avoided ~$16 B/yr of electricity bills.
Net saving (accounting for cost of conservation
measures and programs) is ~$12 B/year, or
about $1,000/family/yr.
Avoids 18 million tons per year of Carbon
Appliance standards save ~$3B/year (1/4)
8. Lighting
Compact Fluorescents or Long Fluorescents using plasma
discharges use only 1/4 of the energy and heat of incandescent
lights, which derive their light from heating filaments hot enough
to emit visible light.
If every home changed their five most used lights, they would
save $60 per year in costs.
This would also be equal to 21 power plants.
The fluorescents also last up to 10 times as long.
Replacing one bulb means 1,000 pounds less CO2 emitted over
the compact fluorescent’s lifetime.
Traffic signal LEDs use 90% less energy and last 10 years rather
than 2 years.
Lloyd Levine, Chair of the India Assembly’s Utility and
Commerce Committee, has proposed the “How Many Legislators
does it take to Change a Light Bulb Act” to ban incandescent
bulbs by 2012.
Australia has just passed a law to ban incandescent bulbs by
2009.
9. Compact Fluorescent Bulbs:
Do the Math for India
Allocate a 125 watt equivalent bulb for sufficient lighting for each
person. Each 125 watt equivalent CFL uses only 30 watts.
(Incandescent bulbs only use 5% of their energy for light).
They will use 30 watts per person and save 125-30=95 watts over
incandescent bulbs.
Multiply by 30,000,000 Indians, saves 3 gigawatts of power
capacity.
3 gigawatts is more than 10% of the nighttime load.
That is equivalent to about three nuclear power plants at one
gigawatt each.
The cost of this is currently $1.70/person x 30 million people is $50
million.
This is equivalent to buying each nuclear power plant for $17
million, rather than $2 billion or more each at current cost estimates.

16. Solar Water Heating
Water heating uses 14-25% of energy use
Solar water heating replaces the need for 2/3 of conventional water
heating.
Virtually all homes in Greece and Israel (700,000) use solar water
heating. Japan has over 4 million units.
The US over a million, with most systems in Florida and India, and
Hawaii has 80,000.
Each saves 1.5 to 2.5 tons of CO2 a year.
Typical cost is $3,000 for 50 square feet.
DOE is trying to lower this to $1,000 to $1500.
Energy saved would be about 3,000 kWh per year per household
DOE would like to have 3 million new units by 2030.
Current payback is 10-13 years (solar lobby says 4-8 years),
whereas for 50% market penetration, 5-6 years is needed.
17. Building energy efficiency
Structural Insulated Panels are 4-8 inches
thick and are foam filled. They can be faced
with drywall and plywood. They give R-4 to
R-8 per inch of thickness.
Insulation includes batts and rolls, loose fill
(blown in), rigid and reflective.
Cool Roofs: white reflective roofs on a
summer’s day lower roof temperature from
150-190° F to 100-120° F. Saves 20% on air
conditioning costs.
20. Energy conserving potential by sector
Industries: 4-8%
Residential: 10-30%, except lighting at 50%
Commercial / Public heating and cooling:50%
Transportation: 10 – 20%
21. Additional Advantages of Energy
Conservation
Less need to secure oil and natural gas overseas
with attendant military and civilian casualties while
costing hundreds of billions of dollars
Fewer power plants and liquid natural gas ports are
needed
Less air pollution
Less drilling for oil in Alaska and near national parks
Less global warming and attendant environmental
destruction
22. Conclusions on Energy
Conservation
Energy conservation has saved the need for many power plants
and fuel imports.
It has also avoided CO2 and environmental pollution.
Energy conservation research is only funded at $306 million this
year at DOE, which is low considering the massive amounts of
energy production that are being saved by conservation.
Regulations on efficiency work, but voluntary efforts lag far
behind.
Much has been done, but much more can be done
In this new era of global warming and high energy costs and
energy shortages, the public must be informed and politicians
sought who are sensitive to these issues.
Editor's Notes
Estimate some of the causes of this 2%/year gain. Each year, the cost of conservation programs, public interest R&D, and standards adds ~1% to electric bills, but cuts 1/2% off the bill. So an investment of $1 in say 1990 saves $.50 per year for 10 to 20 years.
Calif annual electric bill in 2004 ~ $32 B, so we’ve avoided ~$16 B of bills, but net saving is only ~$12B/year, i.e. $1000/family/yr.
