Geothermal Energy Potential
State of Nevada
Discover the geothermal power
generation potential in your state.
Power	Genera*on		
Geothermal	energy	is	heat	from	the	Earth.	
It's	clean	and	sustainable.	Resources	of	
geothermal	energy	range	from	the	shallow	
ground	to	steam,	hot	water,	and	hot	rock	
accessed	by	drilling	wells	up	to	thousands	
of	feet	beneath	the	Earth's	surface.		The	
extremely	high	temperatures	in	the	deeper	
geothermal	reservoirs	are	used	for	the	
generaAon	of	electricity.	
	
Most	power	plants	use	steam	to	generate	
electricity.	The	high-pressure	steam	spins	a	
turbine	that	rotates	a	generator,	producing	
electricity.	The	largest	source	of	carbon	
emissions	in	the	U.S.	are	the	many	power	
plants	sAll	burning	fossil	fuels	to	boil	water	
for	steam.	Geothermal	power	plants,	
however,	do	not	burn	fuels	to	heat	water	
to	steam.		Instead,	they	use	natural	heat	
found	below	the	Earth's	surface	to	
generate	electricity.	
	
New	geothermal	power	plants	produce	
near-zero	CO2	and	emit	very	liKle	air	
polluAon.		
	
And	unlike	solar	or	wind	energy,	
geothermal	energy	is	available	around	the	
clock.	
	
BENEFITS	
Jobs Boost. Geothermal power plants employ about
1.17 persons per MW. Adding related governmental,
administrative, and technical jobs, the number
increases to 2.13.
Economy Boost. Over the course of 30 to 50 years
an average 20 MW facility will pay nearly $6.3 to $11
million dollars in property taxes plus $12 to $22
million in annual royalties. Seventy-five percent of
these royalties ($9.2 to $16.6M) go directly back to
the state and county.
Locally Produced. Geothermal power can offset
electricity currently imported into the state, keeping
jobs and benefits in state and local communities.
Near-Zero Carbon Emissions. Geothermal flash
plants emit about 5% of the carbon dioxide, 1% of
the sulfur dioxide, and less than 1% of the nitrous
oxide emitted by a coal-fired plant of equal size, and
binary geothermal plants – the most common –
produce near-zero emissions.
Small Footprint. Geothermal has among the
smallest surface land footprint per kilowatt (kW) of
any power generation technology.
Reliable. Geothermal power can provide consistent
electricity throughout the day and year - continuous
baseload power and flexible power to support the
needs of variable renewable energy resources, such
as wind and solar.
Sustainable Investment. Energy resource decisions
made now for sources of electric power have 40-50
year consequences, or longer. Using renewables
like geothermal resources avoids "price spikes"
inherent in fossil fuel resource markets. Geothermal
energy is an investment in stable, predictable costs.
Investing in geothermal power now pays off for
decades to come.

Direct	Use	
BENEFITS	
Jobs	Boost.	Direct-use	geothermal	energy	projects	leverage	
exisAng	workforces	and	companies	within	the	state.	Their	
simple	design	and	construcAon	from	off-the-shelf	parts	can	
uAlize	local	engineering	firms,	geologists,	drilling	operators,	
construcAon	trades,	pipefiKers,	technicians,	and	welders.	A	
rough	predicAon	of	potenAal	job	opportuniAes	created	by	
installing	direct-use	systems	may	be	3	temporary	jobs	per	
MWth	during	construcAon,	with	1	full-Ame	job	per	MWth	for	
ongoing	operaAon.	
Economy	Boost.	Geothermal	heated	faciliAes	have	the	
potenAal	to	sAmulate	economies	through	increased	tax	
revenues,	the	creaAon	of	new	businesses	and	local	jobs,		
tourism,	agriculture,	and	enhanced	community	involvement.		
Locally	Produced.	Directly	using	geothermal	energy	in	
homes	and	commercial	operaAons,	such	as	food	producAon	
from	local	agriculture,	can	offset	imported	energy,	keeping	
jobs,	dollars,	and	other	benefits	in	local	communiAes.	
Carbon	Emission	Reduc*on.	Geothermal	direct-use	projects	
produce	near-zero	emissions.		Depending	on	the	exisAng	
heaAng	fuels	being	offset,	this	may	result	in	annual	
emissions	reducAons	of	anywhere	between	1,700	tons	(if	
offsedng	natural	gas)	to	9,300	tons	(if	offsedng	electricity)	
of	CO2	saved	per	MWth	of	installed	geothermal	direct-use	
capacity.		
Flexible	Hea*ng	Systems.	ApplicaAons	of	geothermal	direct	
use	may	include	district	heaAng,	snow	melAng,	spas	and	
pools,	agriculture,	food	processing,	and	other	uses.	Within	a	
single	system	these	diverse	applicaAons	can	be	“cascaded”	
and	work	together	in	the	most	efficient	way	possible	to	
ensure	the	maximum	benefit	and	lowest	costs	possible	from	
direct-use	systems.		
	
Reliable	and	Sustainable	Heat	Source.	Geothermal	heaAng	
projects	last	for	decades—typically	25	years	or	more—
providing	reliable	energy	at	a	low,	stable	price.	This	can	
provide	price	certainty	and	insulate	consumers	(and	the	
economy)	from	ojen	unpredictable	fluctuaAons	in	fossil	fuel	
prices.
	
	
Discover the geothermal direct-use
potential in your state.
Geothermal	energy	is	heat	from	the	
Earth.	It's	clean	and	sustainable.	
Resources	of	geothermal	energy	range	
from	the	shallow	ground	to	hot	water	and	
hot	rock	accessed	by	drilling	wells	up	to	
thousands	of	feet	beneath	the	Earth's	
surface.		The	hoKest	reservoirs	are	used	
to	produce	electricity,	and	the	more	
common	moderately	hot	reservoirs	are	a	
ready	source	of	natural	heat,	without	
burning	fossil	fuels.	
	
Direct,	or	non-electric,	use	of	geothermal	
energy	refers	to	the	use	of	the	energy	for	
both	heaAng	and	cooling	applicaAons.	
Fluids	with	temperatures	of	<300°F,	
adequate	for	direct	use,	are	available	
throughout	much	of	the	United	States.	
	
Direct	use	of	geothermal	energy	in	homes	
and	commercial	operaAons	is	much	less	
expensive	than	using	tradiAonal	fuels;	
savings	can	be	as	much	as	80%!			
Furthermore,	direct-use	applicaAons	such	
as	fish	farms,	greenhouses,	
microbreweries,	fruit	and	vegetable	
drying,	spas,	pulp	and	paper	processing,	
and	lumber	drying	offer	aKracAve	and	
innovaAve	opportuniAes	for	local	
businesses	and	entrepreneurs.

Geothermal	Direct-Use			
Projects	in	Nevada	
The	city	of	Elko	has	two	
geothermal	district	heaAng	
systems	in	place.	A	large,	
privately-owned	system	on	the	
west	side	of	town	provides	
space	heaAng	and	hot	water	to	
residenAal,	commercial	and	
municipal	buildings	such	as	the	
sheriff’s	office	and	the	old	post	
office.	A	smaller	system,	
owned	by	Elko	County	School	
District,	provides	space	heaAng	
to	several	municipal	buildings	
and	heats	the	municipal	pool.	
The	total	esAmated	annual	heat	consumpAon	in	Nevada	is	85	Trillion	
BTU.	Developing	the	hydrothermal	direct-use	resources	in	Nevada	–	as	
much	as	70	Trillion	BTU	-		could	supply	three-fourths	of	Nevada’s	heaAng	
needs	with	clean,	renewable	geothermal	heat.	
	
Nevada’s	CO2	emissions	from	heaAng	are	nearly	5.1	MMtCO2	per	year.		
Developing	geothermal	direct	use	in	the	state	can	reduce	emission	by	
as	much	as	4.1	MMtCO2	per	year,	while	providing	reliable	energy	at	a	
low,	stable	price.

Heat	Pumps	
Discover the geothermal heat pump
potential in your state.
Geothermal	energy	is	heat	from	the	Earth.	
It's	clean	and	sustainable.	Resources	of	
geothermal	energy	range	from	the	shallow	
ground	to	hot	water	and	hot	rock	
accessed	by	drilling	wells	up	to	thousands	
of	feet	beneath	the	Earth's	surface.		
Geothermal	heat	pumps	use	the	natural	
insulaAng	properAes	of	the	earth	from	just	
a	few	feet	underground	to	as	much	as	
several	hundred	feet	deep,	offering	a	
unique	and	highly	efficient	renewable	
energy	technology	for	heaAng	and	cooling.		
	
Most	work	by	circulaAng	water	in	a	closed	
system	through	a	“loop	field”	installed	
horizontally	or	verAcally	in	the	ground	
adjacent	to	or	even	beneath	a	building.		
Heat	is	taken	from	the	building	and	
transferred	to	the	ground	in	the	summer.		
The	system	is	reversible,	and	heat	is	taken	
from	the	ground	and	used	in	the	building	
in	the	winter.		The	system	only	moves	
heat,	which	is	much	more	efficient	than	
using	a	fuel	or	electricity	to	create	heat.	
	
Geothermal	heat	pumps	can	support	
space	heaAng	and	cooling	needs	in	almost	
any	part	of	the	country.	
BENEFITS	
Economic. On average, a typical home of 2000
square feet will require 4 tons of heating and cooling
capacity with an average system installation cost
between $5,000 and $7,500 per ton.
Energy Efficient. Geothermal heat pumps use 25%
to 50% less energy than conventional heating or
cooling systems.
Carbon Emissions Reduction. One ton (12,000
BTU/hr) of GHP capacity over a 20 year operating
cycle avoids 21 metric tons of CO2 emissions. So a
typical home system can avoid 80-100 metric tons of
CO2 emissions.
Improved Indoor Air Quality & Safety. There is no
combustion in a geothermal heat pump; therefore
there is no chance of carbon-monoxide poisoning. By
adding high-efficiency air cleaners with geothermal,
these systems can improve inside air quality.
Locally Produced. Everywhere. Unlike other
geothermal technologies, heat pumps are not limited
by geography or geology. They can be installed in
most locations in any of the 50 states or territories of
the U.S.
Sustainable Investment. The lifespan of a
geothermal system is usually greater than 24 years.
A conventional furnace will last 7-10 years with
regular maintenance. The ground loop of the
geothermal system has a warranty of 50 years.
These loops are made up of high-density
polyethylene pipe, the same pipe which is used in
city gas lines.
Quiet Operation. Unlike air conditioners, there is no
outdoor unit. Geothermal units are very smooth and
quiet in operation.

example,	a	retrofidng	a	fuel	oil	furnace	with	a	GHP	system	will	reduce	
CO2	emissions	by	62%.	
	
Geothermal	Heat	Pumps						
in	Nevada	
Geothermal	heat	pumps	are	
effecAve	for	all	sizes	of	buildings	
from	small	homes	to	large	
buildings.	In	2009,	the	Golden	
Gate	Hotel	&	Casino	in	Las	Vegas	
installed	a	system	that	uses	10	
boreholes.	Tubing	runs	verAcally	
through	the	wells	and	connects	
to	the	heat	pump.	The	system	
harnesses	enough	energy	to	
heat	the	showers	of	106	rooms.	
Household
cost
savings:
$100s in cost
savings each
year
Public	and	commercial	buildings,	such	as	schools,	universiAes,	prisons,	and	
hospitals,	can	be	retrofiKed	with	geothermal	heat	pumps	and	provide	cost-
savings	to	the	state’s	–	and	other	uAlity	rate	payer’s	–	energy	bills.	The	
picture	above	is	an	example	of	a	commercial	size	verAcal	loop	system.	
These	systems	are	quiet,	last	for	several	decades,	and	reduce	the	state’s	
dependence	on	fossil	fuels	for	heaAng	and	cooling	needs.

Geothermal Energy Potential in Nevada: 45% of State's Power Needs

  • 1. Geothermal Energy Potential State of Nevada Discover the geothermal power generation potential in your state. Power Genera*on Geothermal energy is heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to steam, hot water, and hot rock accessed by drilling wells up to thousands of feet beneath the Earth's surface. The extremely high temperatures in the deeper geothermal reservoirs are used for the generaAon of electricity. Most power plants use steam to generate electricity. The high-pressure steam spins a turbine that rotates a generator, producing electricity. The largest source of carbon emissions in the U.S. are the many power plants sAll burning fossil fuels to boil water for steam. Geothermal power plants, however, do not burn fuels to heat water to steam. Instead, they use natural heat found below the Earth's surface to generate electricity. New geothermal power plants produce near-zero CO2 and emit very liKle air polluAon. And unlike solar or wind energy, geothermal energy is available around the clock. BENEFITS Jobs Boost. Geothermal power plants employ about 1.17 persons per MW. Adding related governmental, administrative, and technical jobs, the number increases to 2.13. Economy Boost. Over the course of 30 to 50 years an average 20 MW facility will pay nearly $6.3 to $11 million dollars in property taxes plus $12 to $22 million in annual royalties. Seventy-five percent of these royalties ($9.2 to $16.6M) go directly back to the state and county. Locally Produced. Geothermal power can offset electricity currently imported into the state, keeping jobs and benefits in state and local communities. Near-Zero Carbon Emissions. Geothermal flash plants emit about 5% of the carbon dioxide, 1% of the sulfur dioxide, and less than 1% of the nitrous oxide emitted by a coal-fired plant of equal size, and binary geothermal plants – the most common – produce near-zero emissions. Small Footprint. Geothermal has among the smallest surface land footprint per kilowatt (kW) of any power generation technology. Reliable. Geothermal power can provide consistent electricity throughout the day and year - continuous baseload power and flexible power to support the needs of variable renewable energy resources, such as wind and solar. Sustainable Investment. Energy resource decisions made now for sources of electric power have 40-50 year consequences, or longer. Using renewables like geothermal resources avoids "price spikes" inherent in fossil fuel resource markets. Geothermal energy is an investment in stable, predictable costs. Investing in geothermal power now pays off for decades to come.

  • 3. Geothermal Energy Potential State of Nevada Direct Use BENEFITS Jobs Boost. Direct-use geothermal energy projects leverage exisAng workforces and companies within the state. Their simple design and construcAon from off-the-shelf parts can uAlize local engineering firms, geologists, drilling operators, construcAon trades, pipefiKers, technicians, and welders. A rough predicAon of potenAal job opportuniAes created by installing direct-use systems may be 3 temporary jobs per MWth during construcAon, with 1 full-Ame job per MWth for ongoing operaAon. Economy Boost. Geothermal heated faciliAes have the potenAal to sAmulate economies through increased tax revenues, the creaAon of new businesses and local jobs, tourism, agriculture, and enhanced community involvement. Locally Produced. Directly using geothermal energy in homes and commercial operaAons, such as food producAon from local agriculture, can offset imported energy, keeping jobs, dollars, and other benefits in local communiAes. Carbon Emission Reduc*on. Geothermal direct-use projects produce near-zero emissions. Depending on the exisAng heaAng fuels being offset, this may result in annual emissions reducAons of anywhere between 1,700 tons (if offsedng natural gas) to 9,300 tons (if offsedng electricity) of CO2 saved per MWth of installed geothermal direct-use capacity. Flexible Hea*ng Systems. ApplicaAons of geothermal direct use may include district heaAng, snow melAng, spas and pools, agriculture, food processing, and other uses. Within a single system these diverse applicaAons can be “cascaded” and work together in the most efficient way possible to ensure the maximum benefit and lowest costs possible from direct-use systems. Reliable and Sustainable Heat Source. Geothermal heaAng projects last for decades—typically 25 years or more— providing reliable energy at a low, stable price. This can provide price certainty and insulate consumers (and the economy) from ojen unpredictable fluctuaAons in fossil fuel prices. Discover the geothermal direct-use potential in your state. Geothermal energy is heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock accessed by drilling wells up to thousands of feet beneath the Earth's surface. The hoKest reservoirs are used to produce electricity, and the more common moderately hot reservoirs are a ready source of natural heat, without burning fossil fuels. Direct, or non-electric, use of geothermal energy refers to the use of the energy for both heaAng and cooling applicaAons. Fluids with temperatures of <300°F, adequate for direct use, are available throughout much of the United States. Direct use of geothermal energy in homes and commercial operaAons is much less expensive than using tradiAonal fuels; savings can be as much as 80%! Furthermore, direct-use applicaAons such as fish farms, greenhouses, microbreweries, fruit and vegetable drying, spas, pulp and paper processing, and lumber drying offer aKracAve and innovaAve opportuniAes for local businesses and entrepreneurs.

NREL/AA-AA00-00000 • Month 2015 NREL prints on paper that contains recycled content Carbon emissions reduction: 4.1 million metric tons (MMtCO2) Policies & Incen*ves Federal and state policies and incenAves helped catapult renewable energy technologies, such as wind and solar, into the billion dollar industries they are today. State incenAve programs that help developers reduce upfront risk can help to incenAvize geothermal direct-use development in the state. Reliable, stable heat: 70 trillion BTU Locally produced energy Geothermal Direct-Use Projects in Nevada The city of Elko has two geothermal district heaAng systems in place. A large, privately-owned system on the west side of town provides space heaAng and hot water to residenAal, commercial and municipal buildings such as the sheriff’s office and the old post office. A smaller system, owned by Elko County School District, provides space heaAng to several municipal buildings and heats the municipal pool. The total esAmated annual heat consumpAon in Nevada is 85 Trillion BTU. Developing the hydrothermal direct-use resources in Nevada – as much as 70 Trillion BTU - could supply three-fourths of Nevada’s heaAng needs with clean, renewable geothermal heat. Nevada’s CO2 emissions from heaAng are nearly 5.1 MMtCO2 per year. Developing geothermal direct use in the state can reduce emission by as much as 4.1 MMtCO2 per year, while providing reliable energy at a low, stable price. Low-temperature hydrothermal potenAal exists throughout most of the state of Nevada with several hundred locaAons idenAfied by the USGS as having potenAal for development.

  • 5. Geothermal Energy Potential State of Nevada Heat Pumps Discover the geothermal heat pump potential in your state. Geothermal energy is heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock accessed by drilling wells up to thousands of feet beneath the Earth's surface. Geothermal heat pumps use the natural insulaAng properAes of the earth from just a few feet underground to as much as several hundred feet deep, offering a unique and highly efficient renewable energy technology for heaAng and cooling. Most work by circulaAng water in a closed system through a “loop field” installed horizontally or verAcally in the ground adjacent to or even beneath a building. Heat is taken from the building and transferred to the ground in the summer. The system is reversible, and heat is taken from the ground and used in the building in the winter. The system only moves heat, which is much more efficient than using a fuel or electricity to create heat. Geothermal heat pumps can support space heaAng and cooling needs in almost any part of the country. BENEFITS Economic. On average, a typical home of 2000 square feet will require 4 tons of heating and cooling capacity with an average system installation cost between $5,000 and $7,500 per ton. Energy Efficient. Geothermal heat pumps use 25% to 50% less energy than conventional heating or cooling systems. Carbon Emissions Reduction. One ton (12,000 BTU/hr) of GHP capacity over a 20 year operating cycle avoids 21 metric tons of CO2 emissions. So a typical home system can avoid 80-100 metric tons of CO2 emissions. Improved Indoor Air Quality & Safety. There is no combustion in a geothermal heat pump; therefore there is no chance of carbon-monoxide poisoning. By adding high-efficiency air cleaners with geothermal, these systems can improve inside air quality. Locally Produced. Everywhere. Unlike other geothermal technologies, heat pumps are not limited by geography or geology. They can be installed in most locations in any of the 50 states or territories of the U.S. Sustainable Investment. The lifespan of a geothermal system is usually greater than 24 years. A conventional furnace will last 7-10 years with regular maintenance. The ground loop of the geothermal system has a warranty of 50 years. These loops are made up of high-density polyethylene pipe, the same pipe which is used in city gas lines. Quiet Operation. Unlike air conditioners, there is no outdoor unit. Geothermal units are very smooth and quiet in operation.
  • 6. Policies & Incen*ves Federal and state policies and incenAves helped catapult renewable energy technologies, such as wind and solar, into the billion dollar industries they are today. States can use tax incenAves, including property and sales tax incenAves, and tax credits to provide an incremental moAvaAon for geothermal development. 0% 20% 40% 60% 80% 100% Electric heat pump Electric heater Natural gas furnace Propane/LPG furnace Fuel oil furnace Original System Retrofit GHP System Percentage reducAon of CO2 emissions from a geothermal heat pump (GHP) retrofit for a typical home in the Western United States. For example, a retrofidng a fuel oil furnace with a GHP system will reduce CO2 emissions by 62%. Geothermal Heat Pumps in Nevada Geothermal heat pumps are effecAve for all sizes of buildings from small homes to large buildings. In 2009, the Golden Gate Hotel & Casino in Las Vegas installed a system that uses 10 boreholes. Tubing runs verAcally through the wells and connects to the heat pump. The system harnesses enough energy to heat the showers of 106 rooms. Household cost savings: $100s in cost savings each year Public and commercial buildings, such as schools, universiAes, prisons, and hospitals, can be retrofiKed with geothermal heat pumps and provide cost- savings to the state’s – and other uAlity rate payer’s – energy bills. The picture above is an example of a commercial size verAcal loop system. These systems are quiet, last for several decades, and reduce the state’s dependence on fossil fuels for heaAng and cooling needs.
