coal will continue to be used by developing nations as primary energy source
First part: human health impacts due to burning coal in coal stoves in homes
Coal combustion in homes has caused severe human health problems due to high levels of arsenic, fluorine, selenium, and mercury
groundwater leaches toxic organic compounds from coal causing adverse health conditions such as: Balkan endemic nephropathy (found mainly in rural communities in Bosnia, Bulgaria, Croatia, Romania, Serbia

This study focuses on long-term exposure of PM2.5 or less
data collected after new standard for PM2.5 in place- requiring sites to collect data on this size
assessing mortality of target areas
generated models based on different levels of PM2.5 in different decades
Overal PM2.5 decreased over time- largest decrease observed in cities with highest levels of pollution in 1979-1983 years
Several great figures to view comparable mortality levels- stepwise regression for demographic factors and smoking vs former smoker vs non-smoker
Shows high association of risk for lung cancer and cardiopulmonary mortality and long-term exposure to fine particulate matter
doubling the time of follow-up researchers saw mortality numbers triple due to the causes listed above- relative to other studies

Buhre, B., Hinkley, J., Gupta, R., Wall, T., Nelson, P. "Submicron ash formation from coal combustion," Fuel, 84(10), 1206-1214.
submicron sized particulate matter are primarily formed by volatilised ash, soot, and char particles
This is experiment that burns bituminous coals to determine influence of coal characteristics and combustion environment on submicron ash yield
obtained ash with different chemical compositions due to varying combustion environments
This experiment does not address health implications of they different kinds of ash formed during combustion; in some cases, less volatile material was transformed to higher volatile material due to conditions

air pollution from combustion of fossil fuels causes range of adverse health effects from "eye irritation to death"
man-made combustion of fossil fuels creates mixture of toxic chemicals, namely particulate matter
study focuses on mortality (death) due to inhaled particulate matter
mortality in this study is due to cardiopulmonary, lung cancer, or acute respiratory infections in children
results include: 3% of adult mortality due to cardiopulmonary, 5% of lung cancer (includes tracheal, bronchial), 1% acute respiratory in children
0.8 million premature deaths and 6.4 million lost life years (not really defined here)
author's point their results may be underestimation of what is actually occurring (due to fact that they only assessed mortality- not acute infections or serious morbidity)
great mortality rates found in developing countries

energy production/use poses health risks through industrial hazards, pollution, and injury
while substantial burden on a global scale, there are differences between rich and poor nations
climate change effects- flooding, acid rainfall, droughts, extreme weather events that all have adverse effects on populations
risks associated with energy are found in extraction, transportation, and burning of fossil fuels
80% of energy use is oil, gas, and coal
risks from drilling, mining, and harvesting of resources are less than risks from other steps in the fuel cycle
risks lessened from fossil fuel burning in developed nations, however developing nations see rapid growth coupled with low environmental regulations so high risk
16/20 most polluted cities are in china- see page 7 for numbers of lives lost or years lost due to pollution
climate change deaths-cited in paper from WHO- is ~150,000, 99% of these are in poor countries- this is 2000 data

Used populations with varying distances from plant
Factored in air pollution control technologies
~6000 to 10,700 annual deaths to air pollution from these 88 plants
Table 1 provides great breakdown of top three emissions from coal: PM, SO2, NO2 and the attributable health outcomes plus mortality in each case
estimate that if all 88 plants used pollution control, deaths would drop to ~2710

high risk of cardiovascular disease (CVD) correlated with coal mining areas
factors include environmental, behavioral, genetic, demographic, and available healthcare
Coal mining areas linked to low socioeconomic status relative to non-coal mining areas
elements that contribute to CVD: arsenic, cadmium, non-specific particulate matter, and polycyclic hydrocarbons- all present in coal and introduced to areas with coal extraction and processing
Study controls for factors such as smoking, obsesity, co-morbid diabetes, alcohol consumption (does a before and after)
after adjusting for other factors, risk of CVD remained high in coal mining areas of Appalachia
study found that environmental pollution attributed to higher prevalence of CVD risk; however coal mining risks were also specific to Appalachia and not other mining (does not specify what kind of mining) regions in U.S.
uses self-reported data- so does not include mortality rates in coal-mining areas of Appalachia

This study models and monetized damages associated with coal-fired plants across U.S. (407 power plants to be exact)
Focus on PM2.5 (fine particle) and its health related effects, provide estimate of economic value of a statistical life, used 1999 PM2.5 levels
Used emissions from electricity generation, coal had to be primary fuel; 407 plants with three indicators- 11.7 million tons of sulfur dioxide, 5.0 million tons of nitrogen oxides, 600,000 tons of PM2.5, selected plants emitted over 90% of the national PM2.5, SO2 emissions
Variation of previous study-slope changes of 10, 15, 20, 25, 30 micrograms/meters cubed; found a 1.2% increase in mortality per microgram/m-cubed increase of annual average PM2.5-by characterizing uncertainty as within individual plants as well as across all plants; factors in population exposure
Calculated median health-related damages- based on 1999 emissions: $0.02-$1.57 per kWh with highest values found in Midwest
Damages per kWh: 75% of total for sulfur dioxide, 14% for PM2.5, 8% for nitrogen oxides (if want specifics, ranges are provided for each on pg 1010
Study finds that improvements to technologies (again based on 1999 data) would result in ~2000 fewer deaths per year

PM2.5 leads to 800,000 premature deaths per year (13th leading cause of worldwide mortality)- main source is combustion of fossil fuels
short-term PM exposure: cardiovascular diseases account for 69% of increase in mortality rates, 28% for pulmonary diseases
Table 3- great summary of several studies on mortality increases with exposure to PM2.5
Long-term exposure to PM2.5 decreases life expectancy from months to several years

Public health impacts of fossil fuel based power generation represent 70% of the external costs associated
There are direct health impacts due to particulate matter and other emissions during power generation
Cited 2010 National Research Council: 2005 total costs of externalities total $120 billion (double check to see if these are valuation estimates or include costs such as hospital/medical charges
Same source to double check $30/ton of carbon dioxide climate related damages
Environmental burden of disease, disability adjusted life years and total mortality all included in results
Figure 2- good description of life expectancy and infant mortality over time
Results: coal consumption negatively affects health; even with controls to reduce PM and sulfur oxides, coal plants still generate large amounts of air pollution; more carbon intensive than any other energy system

Coal predominant fuel for electric generation
2005- coal use generated 7334 TWh, 7.856 Gt carbon dioxide emissions from electricity, 3.124 Gt of carbon dioxide from non electrical generation
coal mined in 25 U.S. states, with Appalachia comprising newer mining models- mountaintop removal
Coal produces 1.5 times more carbon dioxide emissions than oil, and 2x more than natural gas
Coal mining and combustion releases harmful materials that affect the climate, toxic metals and particulate matter- harms public health,ecological systems
This study conducts a life cycle analysis of coal- measurable, quantifiable, and qualitative costs of coal
Climate impacts for social costs of carbon=- $30/ton of carbon range from $10-$100
Hazards come from extraction, processing, transportation, combustion, occupational hazards from underground mining, mountaintop removal
great table on pages 78-79 of economic, human health, and environmental effects at each stage of the coal life cycle
coal produces damages ~$2.2 billion in social costs from carbon
coal combustion waste or fly ash- toxic chemicals and heavy metals- cancer, birth defects, reproductive disorders, neurological damage, development issues, kidney and diabetes
includes local water contamination, carcinogen emissions, and community health effects
ecological impacts reviewed if necessary
combustion- carbon dioxide, methane, particulates, sulfur and nitrogen oxides, mercury- reviews effects from each
huge contributor to climate change
conclusion from life cycle analysis: $345.3 billion- 17.8 cents/kWh. Low estimate: $175 billion, a little over $0.09/kWh (these are conservative estimates where closer costs amount to $523.3 billion, $0.27/kWh

ambient PM2.5 associated with premature death and morbidity outcomes
This study looks at several sectors of PM2.5- based on 2005 emissions- since replacing coal with PV as source of electrical generation, focusing only on electrical sector
Table 3 shows total PM2.5 concentrations, based on population. Electrical sector: 2.27 of 8.73 microgram per meter cubed- this was largest contribute to PM2.5 in 2005

Provides great picture of fuel cycle- primary and secondary coupled with adverse health effects at each stage
Electricity considered secondary source of energy as traditionally formed from combustion of fossil fuels
Factor in household fuel use- such as coal for cooking- indoor air pollution here
Health effects from fossil fuels span across life cycle: mining to transport to combustion to waste management
Coal: major energy source: ~25% energy use, ~40% of electrical use, ~40% contribution to climate change through carbon dioxide
Coal mining dangerous to workers: ~15,000 mining injuries per year, ~3800-6000 premature deaths per year in China (numbers correct have direct source in lit rev)
Injuries from mining accidents (explosions, floods, falling rocks, misuse of machinery) and respiratory exposures to silica and coal dust, along with risk of lung cancer
Areas near coal mining operations report higher risk of CVD, pulmonary, kidney diseases
Once transported for electricity- occupational hazards include:dust and carcinogen exposure
Combustion: cited as heaviest health burden- double check source- carbon dioxide, carbon monoxide, sulfur and nitrogen oxides, particulate matter, mercury, other metals
Particulate matter: results in acute and chronic death; no well defined safe threshold for PM
Small assessment on solar: major health concern is related to the crystalline silicon, other materials such as: copper indium diselenide, copper indium galium diselenide, gallium arsenide, and cadmium telluride
Mining for silica risk of silicosis (lung disease caused by inhalation), exposure to toxic metals (cadmium, arsenic,chromium, lead) and gases (arsine, phosphine, silane) during manufacturing
Cited that health impacts of solar are far less than any fossil fuel

Will focus on electrical generation sector for this paper
data from 2005
Looks at premature mortalities (death): spatial and temporal factors included in this model
Electrical generation responsible for 75% of health impacts- due to sulfur dioxide emissions
electrical power generation 4x the emissions in the summer than in the winter- this does not align with other research, however this is more recent
combustion emissions: 12% from California, 7% from Pennsylvania, 5.8% from Ohio

emissions of normal operation of power plants contributes to increased mortality and morbidity
This study includes results from both Europe and China
mortality is expressed in years of life lost (YOLL) per kwh
coal power plants without emission reduction yield highest health damages per unit of electricity produced
provide great figures to show fatalities per kWh due to accidents, life years lost, disability adjusted life years- for several types of fossil fuel combustion
Premature fatality caused by air pollution corresponds to roughly 10 life years lost
ulitmately- fatality rates due to normal operation are much higher than due to accidents- waiting to interpret numbers
Alsema, E. (2000). "Energy Pay-back Time and CO2 Emissions of PV Systems," Progress in Photovoltaic Research and Applications,8(1), 17-25.
Emission and energy pay back addressed here; emissions focused only on production of pv modules
energy required to produce multicrystalline: 2400-7600 MJ/meters squared, for single-crystalline: 5300-16500 MJ/meters squared
Energy pay back period- a concern when considering alternative technologies
Present day systems (point this is in 2000) is 3-4 years, may have improved since then; projected to decline to 1-2 years
Figure 2 provides carbon dioxide emission of rooftop solar: in 1999 mc-silicon 50 kWh/m2/yr; projected this to decrease to 30 in 2010; again numbers may have improved significantly more since then

looking at improvements in air quality's effects on daily mortality and life expectancy
1980's Ireland shifted from oil to combustion of coal
1990 government banned use of bituminous coal (black coal) in Dublin- study compares levels of pollution before and after ban
totaled individuals who died of respiratory infection/disease, cardiovascular, cerebrovascular
Found: pollution declined following ban of combustion of black coal
found: overall decline in mortality, largest reduction found in seasons where coal use was highest (winters, spring)- significant results found 403 fewer deaths per year following bituminous coal ban

In 2003, energy industry contributed 74% to global carbon dioxide emissions
This includes transportation
This study is conducted in Lebanon- could be used as case study, but maybe not overall numbers
Author suggests solar is most promising renewable source in middle east, but does not think it will penetrate market due to investment costs
Estimates that solar if only 5% of energy generation from solar- reduction to 832 Gg/year in carbon dioxide emissions
Tsoutsos, T., Frantzeskaki, N., Gekas, V. (2005). "Environmental impacts from the solar energy technologies," Energy Policy, 33(3), 289-296.
Positive environmental impacts
Reduced carbon dioxide emissions, generally see absence in air and waste emissions
reclamation of degraded land
reduction of transmission lines from traditional electric grid
improved quality of water
positive socioeconomic impacts
increase national energy dependency (still only at regional level)
increase jobs
diversify and secure energy supplies
support deregulated energy markets
more advantages located in generic issues section- provide how solar improves site conditions, flora fauna, etc
Negative impacts addressed depends on size and nature of project
pollutant from leakage of coolant change (double check)
accidental release of chemicals- during operation pv systems do not emit these things, however this could occur with improper management and operation practices
land use- large projects reduce cultivable land (later could site agriphotovoltaics?)
visual intrusion- able to incorporate solar into building designs
occupational hazards: accidental release of heat transfer fluids, fatal accidents (minimal) with use of liquid sodium system, light intensities that damage eyesight
water pollution due to thermal discharges or accidental discharges, air pollution: transport emissions, otherwise low
loss of habitat: counter with environmental impact statements for areas to avoid
deplete natural resources: research underway to reduce these impacts
provides solutions for most the environmental issues addressed above

looks at entire life cycle to account for all ghg emissions
EU has a measure: External Costs of Energy for energy projects
This assessment- in 2003 showed PV in Germany emitting 180g carbon dioxide/kWh (double check against other sources), also showed toxic gas emissions
This study readdresses this as the methodology of the ExternE may not be entirely accurate
Life cycle of solar PV: material production, module production, balance of system production, system operation and maintenance, system decomissioning, and disposal or recycle
GHG emissions involved: 18 g carbon dioxide/kWh (cited from another study- double check), other studies find 12 g carbon dioxide/kWh
Total energy required in life cycle of U.S. cadmium tellurdie PV was 1200MJ/meters squared
Total GHG involved in BOS(balance of system production) was found to be an avg of 24 g carbon dioxide/kWh for utility grounded and 20 g carbon dioxide/kWh for residential rooftop (These are U.S. numbers)
European modules has less carbon involved and numbers are around 16 g carbon dioxide/kWh
did not really break down where these numbers come from- only show final/totals
Fthenakis, V., Chul Kim, H., Alsema, E. (2008). "Emissions from photovoltaic life cycles," Environmental Science and Technology, 42(6), 2168-2174.
Taking into account full life cycle of solar- can have emissions
fossil fuel energy to create solar
Life cycle studies on crystalline silicon, fewer studies on thin film solar pv
Energy payback times for silicon: roughly 3.5 years (double check) for thin film: range from 1.1-2.7 years
Look at four commercial PV systems: ribbon-silicon, multicrystalline silicon, monocrystalline silicon, and thin-film cadmium telluride
Most emissions are indirect due to use of fossil fuels to generate energy
direct emissions come from mining for metals- although noted: liquid and solid waste are mostly recycled
Life cycle steps-brief
mining for quartz sand for silicon, and metal ore for cadmium telluride
heating to obtain optimal silicon structure
cadmium telluride; smelting from zinc and copper
production of polycrystalline silicon most energy consuming stage
2004 greenhouse gas emissions of silicon modules are within 30-45 g carbon dioxide equivalent per kWh, 24g carbon dioxide equiv per kWh for cadmium telluride
Direct cadmium emissions during whole life cycle estimates: 0.015 g/GWh during mining, smelting, purification, and synthesis, 0.004 g/GWh during manufacturing, accidental release: 0.02 g/GWh. This estimates to 90-300 times lower than emissions from coal
Indirect cadmium emissions: researchers concluded that cadmium telluride PV displacing other electricity prevents significant amount of Cd from being released to the air;
Great figures (4 and 5) show emission breakdown for metals in pv life cycle
Katzenstein W., Apt, J. (2009). "Air emissions due to wind and solar power," Environmental Science and Technology, 43(2), 253-258.
A study that looks at emission changes when renewables (wind and solar) involved in cogeneration- natural gas
natural gas plant is used as baseload- generates when solar and wind not generating
Looked at only carbon dioxide and nitrogen oxide emissions- issue- maybe should have looked at methane emissions as well that comprise greenhouse gases
different variables of renewable penetration- below 65% penetration found smaller reduction in nitrogen oxides
carbon dioxide reductions from wind or solar paired with natural gas baseload: 75-80%
does not address other emissions when using alternative generation to fill-in for renewables when they do not generate
Pope, C., Ezzati, M., Dockery, D. (2009). "Fine-Particulate Air Pollution and Life Expectancy in the United States," The New England Journal of Medicine, 360, 376-386.
Question of study: "Do improvements in air quality result in measurable improvements in human health and longevity?"
assessed associations between life expectancy and fine-particulate matter
life expectancy not explicitly defined in article- how long individual will live based on external factors
study from years 1980-2000
PM2.5 concentrations declined from 1980's to 1990's- correlating with: increased life expectancy
10 microgram/ meters cubed increase in PM2.5 resulted in 1-2 years decrease in life expectancy (avg)
10 microgram/meters cubed decrease in PM2.5 resulted in 0.61 year increase in life expectancy, avg increase in life expectancy from 1980-2000 was 2.72 years

noted that solar PV does emit greenhouse gases
briefly address synthesis of PV module using silicon solar cells
Life cycle analysis for amorphous, mono-crystalline, poly-crystalline, and other PV modules
Amorphous: energy consumption for PV plant- 13,000-21000 kWh/kWp, carbon dioxide emissions- 3.360 kg-CO2/kWp, energy pay back period 2.5-3 years for rooftop (with 50-60 g/kWh carbon dioxide emissions in 2010), 3-4 for ground mounted
Mono-crystalline: carbon dioxide emissions: 5.020 kg-carbon dioxide/kWp, energy pay back ~4 years- (provide different systems for different years with very different carbon dioxide emissions
Poly-crystalline: energy pay back- 3.3-4.1 years, again shows very different ares of power systems with very different GHG emissions
addresses tradeoffs such as: efficiency vs emission to produce and use, in the different modules
Ranges are for (1) 15.6-50 gcarbon dioxide/kWh, (2) 44-280 g carbon dioxide/kWh, (3) 9.4-104 g carbon dioxide/kWh
paper recommends using solar pv for drastic carbon dioxide reduction

Carbon dioxide levels for different regions presented in table 4: these include OECD countries, China, the rest of the world, and world totals
Solar water heating system (100 L per day capacity) can mitigate 1237 kg of carbon dioxide emissions (check sources- as this is review)
Solar thermal power- does not provide mitigation- table 5 shows emissions in comparison to coal-natural gas turbines
Solar PV- diesel operated solar pv pump mitigates 2085 kg carbon dioxide, petrol operates mitigates 1860 kg carbon- again check sources
provides similar data for other alternatives- could be used in discussion to provide support for solar pv

Looking at geographic areas of importance: forest, grassland, desert shrubland, true desert, and farmland (biodiversity, biomass density, and cloud cover)
Impacts include: land use, human health and well-being, wildlife and habitat, geohydrological resources, climate and greenhouse gases
For this paper, will only look at human health and well-being and climate and greenhouse gases (others can be revisited for the discussion/conclusion sections
Good table that lists human impacts on page 3265
Most impacts are positive;checkout sources that provide numbers for emissions reductions;
in some cases solar is considered "out of bounds" either due to ecosystem impacts or visual and recreational impacts; does not go into full detail, however provides why solar would be better option to open up recreation in other areas (e.g. mercury reduction for more fishing, reduce mountaintop mining)
reduces carbon dioxide (more research needs for solar in forests- although large solar plant in forest seems counterintuitive...
Table 4- shows emissions of carbon dixoxide from the full ife cycle of large-scale solar: overall- much lower than fossil fuels

This source is being utilized to double check evidence cited in another paper
will focus on the emissions released by developing utility scale solar
USSED uses dust suppressants for industrial applications: water, salts and brines, nonpretroleum products, synthetic polymers, organic petroleum, electrochemical substances, clay additives, and mulch/fiber mixtures
utilized dust suppressants did have an effect on hydrology- increased runoff volume
evidence from this paper is negative impacts on wildlife- could be good in discussion to show potential arguments against solar transition

market penetration: 1.4 GW global solar in 2000 to 40 GW in 2010.
Could use this- what lives saved as of now, how much more do we need to go
provides cost competitiveness of solar
cost of solar declining so rapidly
cost of air pollution due to fossil fuels: range from $0/tcarbon dioxide to $100/ tcarbon dioxide
did not discuss GHG mitigation in depth- only noted that these emissions are zero when in operation, minimal during production

Population size widely viewed as important driving force of future emissions
This study focuses on demographic changes and effects on carbon dioxide emissions from energy production
as expected- decrease in rate of population growth has potential to reduce global emissions
urbanization leads to increase in emissions- also as expected
solutions involved population and economic policies to reduce growth at both levels in hopes that future will see decrease in global carbon dioxide emissions

Utilize article to show advantages and disadvantages of alternatives- why is solar better
This article provides projects on deaths and GHG emissions if nuclear power were completely eliminated
calculated 1.84 million deaths prevented by nuclear- years range from 1971-2009- historical data
Calculated nuclear causes 4900 deaths- again from 1971-2009- compare to solar- historical data
Also provide projections: prevented deaths from 2010-2050: 4.39-7.04 million (low-high end projections)
GHG emissions: historical data 1971-2009: prevented 64 gigatonnes of carbon dioxide
Projections for 2010-2050: will prevent 150-240 gigatonnes of carbon dioxide
does not address externalities associated with nuclear power

provides life cycle analysis of both crystalline and thin film pv modules
ultimately energy payback is significant as it is a policy dispute on whether to adopt technology
GHG emissions in US were reported to be 22-49 g co2 equivalent/kWh
energy pay back in US: 2.5-4.9 years; obviously this will vary depending on irradiance of area- seems to be higher with lower irradiance
breakdown of energy pay back and emissions for silicon and thin film- above is used a general measure

Evaluate and quantify the indirect impacts on the atmosphere of large-scale solar
Focus on rooftop solar in Los Angeles
Measure albedo changes in response to solar
Does large-scale solar generate larger heat islands?
impacts on albedo and consequent heat islands due to 10% efficient large scale solar are virtually non-existent
Albedo remains essentially the same with or without the presence of solar in urban areas
Similar results for 15%, but for 20%- saw some evidence of cooling
Also provide estimates for future, with reasonable deployment and high deployment of PV cells
Results show: no negative effect (on atmospheric conditions) by deploying large scale solar

Figure 2- great image of all impacts
Several impacts worth mentioning- for sake of this project will pull only those related to human, climate impacts
Human Health and Air Quality
Hazards to air quality, health of employees, public- through industrial sized utility
Release soil-born pathogens
Increases in PM2.5 (will double check sources cited on this
decreases in visibility for drivers (double check source for clarification)
soil disruption contaminates water reservoirs and air quality
Positive- recycle of materials during decommissioning
Rooftop Solar PV shown to reduce heat flux- decreasing illness and mortality
Utility-scale solar and Albedo
reflectivity and solar conversion efficiency- tend to have an effective albedo- shows to increase temperatures
However other studies show no effect on air temperatures, or creating heat islands- double check sources
Overall- solar can have significant positive effects on atmosphere land relations- reduced impacts on climate change are 30 times lower than increased impacts of reduced albedo
High ambient temps reduce PV efficiency-? go in depth
Take a look at alternative source to confirm- if PV took up 10% of grid, carbon dioxide reduced from 6.8%-18.8%
