Permit Types:
- Exploration Permit:Non-exclusive and focused on data-gathering. This allows for less intensive prospecting activities and may qualify for exemption under the California Environmental Quality Act.
- Prospecting Permit for Exploration: Requires California Environment Quality Act review. If provided as a term of the permit, may provide for a preferential right to lease.
Lease Types:
- Preferential Right to Lease:The permittee, as the first qualified, has the right to apply to the Commission for a geothermal lease before applications by other entities may be considered.
- Lease Issued by a Competitive Bidding Process:The lease is awarded to the highest bidder.
- Negotiated Lease:Used when lands are unsuitable for competitive bid due to their small size or other factors. Also issued when the State owns a fractional interest in the lands, or in any situation when the lease is determined to be in the best interests of the State.
A lease authorizes exploratory drilling or production. Some leases may produce under a unitization agreement. Unitization is considered when wells drilled upon private or public lands, including State-owned lands, may drain the geothermal resources from state-owned lands. Under a unitization agreement, the State is paid a percentage based on the leased acres.
Existing law requires lessees to pay a minimum 10 percent royalty rate on the gross value of steam or brines when no minerals are extracted (usually where the resource is used for heat or electricity generation). Leases issued by competitive bid have a maximum royalty rate of 16-2/3 percent, which is in addition to a biddable factor (typically a cash bonus or percentage of net profit). Existing law establishes a minimum 2 percent royalty rate on the gross revenue from the sale of mineral products or chemical compounds recovered from geothermal fluids (e.g., lithium, zinc, manganese).
FAQs
Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is a renewable energy source because heat is continuously produced inside the earth. People use geothermal heat for bathing, for heating buildings, and for generating electricity.
What state is #1 in geothermal energy? ›
1. California
The Golden State accounts for 69.5% of the nation's geothermal power.
How much is the efficiency of geothermal plant 28% 15% 42% 30%? ›
Solution: Geothermal power plants have lower efficiency relative to other thermal power plants, such as coal, natural gas, oil, and nuclear power stations. It is commonly assumed that only 15% of the energy from the produced geothermal fluid can be converted to electricity.
Why don't we use geothermal energy? ›
1. Location Restricted. The largest single disadvantage of geothermal energy is that it is location specific. Geothermal plants need to be built in places where the energy is accessible, which means that some areas are not able to exploit this resource.
What are the pros and cons of geothermal energy? ›
Pros and cons of geothermal energy
| Pros Of Geothermal Energy | Cons Of Geothermal Energy |
|---|
| Reliable source of power | Location dependent |
| Small land footprint | High initial costs |
| Usable for large and small-scale installations | Can lead to surface instability |
| The geothermal energy industry is expanding | |

With more than 650 active, high-temperature (fluids over 212 degrees F) wells that tap into geothermal fields, California is the largest generator of electricity from geothermal energy in the United States.
Does California have a lot of geothermal energy? ›
California has two of the largest geothermal reservoirs in the United States, the Salton Sea resource area and the Geysers, with an estimated generation capability of 2,200 MW and 1,800 MW respectively.
How many geothermal plants does California have? ›
California is home to the greatest number of geothermal power plants in the United States. As of 2021, there were 30 such plants operated by electric utilities in the state.
What is the most efficient geothermal power plant? ›
Results show that the binary power plant has the best performance and lowest cost compared with other geothermal power plants analyzed, and there is a reduction in the total power generation cost when using renewable energy sources.
What is the estimated lifespan of a geothermal power plant? ›
What is the average lifespan of a geothermal system? Whether it is a domestic installation or a large-scale plant, the average service life of geothermal systems is very long. The exact numbers vary somewhat: heat pumps generally last 15 to 20 years, while the benchmark lifecycle for larger power systems is 30 years.
For example, a 1 megawatt (MW) binary cycle geothermal power plant can have a cost range between $4 million to $10 million, while a 1 MW direct use or flash steam power plant can have a cost range of $3 million to $8 million.
What is the biggest problem with geothermal energy? ›
Air and water pollution are two leading environmental issues associated with geothermal energy technologies. Additional concerns are the safe disposal of hazardous waste, siting and land subsidence. Most geothermal power plants require a large amount of water for cooling or other purposes.
What is a major drawback of geothermal energy? ›
One of the biggest disadvantages of geothermal energy is that its adoption has many limitations: the location of power plants needs to be close to the boundaries of the tectonic plates while making sure that the level of CO2 inside the geothermal reservoirs is low.
How long does it take to install a geothermal heat pump? ›
Each stage of a geothermal installation can be expected to take the following lengths of time but can vary depending on the site: Permitting and Design – 1 Day to 4 Months depending on the town. Drilling – 3 to 10+ days. Trenching Between Boring and House – 1 to 2 Days.
Is geothermal energy the answer to climate change? ›
Unlike fossil fuels, geothermal energy is a renewable resource that does not emit the greenhouse gases that cause climate change.
What is the conclusion of geothermal energy? ›
Conclusion. Geothermal energy comes from heat in the Earth's core which was generated by the radioactive decay of materials when the planet formed. This thermal energy, stored by rocks and fluids at the centre of the Earth, can be used as a renewable energy resource.
What is the energy of geothermal energy? ›
Geothermal energy is heat that is generated within the Earth. (Geo means “earth,” and thermal means “heat” in Greek.) It is a renewable resource that can be harvested for human use. About 2,900 kilometers (1,800 miles) below the Earth's crust, or surface, is the hottest part of our planet: the core.
What are the 3 main uses of geothermal energy? ›
Geothermal energy can heat, cool, and generate electricity: Geothermal energy can be used in different ways depending on the resource and technology chosen—heating and cooling buildings through geothermal heat pumps, generating electricity through geothermal power plants, and heating structures through direct-use ...
