Another aspect of wind turbine operation and maintenance that differs from that of fossil and nuclear power plants is lubrication. A significant quantity of lubricating oil is placed in the gearbox of a typical wind turbine. The lubrication system incorporates oil filters, and lubricant is either pumped through the system or gravity fed, depending on the turbine type. The smaller turbines built in the mid-1980s had gearboxes that held about 10 gallons of oil or less. Newer, larger devices may handle up to 60 gallons of liquid.
According to Brogna, one school of thinking maintains that lubrication should not be an issue provided the unit is designed correctly. According to him, a second school of thought contends that lubricants must be changed and upgraded to satisfy the specific needs of wind turbines.
A wind turbine consumes how much hydraulic oil?
For lubrication, each wind turbine requires 80 gallons of oil, which is not vegetable oil but a PAO synthetic oil based on crude 12,000 gallons. That oil must be replaced once a year.
A wind turbine can replace how many barrels of oil?
Offshore wind turbines may produce green energy, but they consume far more oil than their proponents disclose.
According to calculations released by Forbes on Wednesday, just laying the foundation for a single offshore turbine can require 18,857 barrels of marine petroleum during construction. Offshore wind farms frequently feature over 100 turbines, implying that only to power the ships involved in construction, about 2 million barrels of gasoline are required.
The Long Island-New York City Offshore Wind Collaborative will cost $1 billion to build and generate 200 megawatts of electricity, enough to power between 40,000 and 64,000 houses depending on the amount of wind that blows during the year.
According to calculations by the Daily Caller News Foundation, the wind farm’s power will cost about $25,000 each property it serves.
The first offshore wind farm in the United States will cost $17,600 per home it will power near Block Island, Rhode Island.

You can rely on our technology leadership and application knowledge to keep your wind turbines working at optimal efficiency, whether onshore or offshore.
Is it possible for wind turbines to spill oil?
Wind turbine oil leaks can damage soil and water. Green lubricants, on the other hand, can be used to avoid this. If they leak, they do not pollute the environment and disintegrate organically.
What is the time it takes for a wind turbine to pay for itself?
Environmental lifespan assessments of 2-megawatt wind turbines proposed for a big wind farm in the US Pacific Northwest were conducted by US academics. They conclude in the International Journal of Sustainable Manufacturing that a wind turbine with a 20-year working life will provide a net benefit within five to eight months of being put online in terms of cumulative energy payback, or the time it takes to produce the amount of energy required for production and installation.
What is the average price of a wind turbine?
If there is no cost or environmental benefit to putting wind on a system with plenty of hydro, one might wonder why we are doing it. The explanation is that many jurisdictions (Washington and California, for example) have established legislation that exclude current hydropower from the legal definition of renewable energy. Many readers may be surprised to learn that existing hydro meets the requirement of being naturally replenished. Existing hydro is replenished in the same way as new hydro would be.
The BPA grid currently has 3000 MW of wind energy potential (when the wind is blowing). Assuming the above-mentioned windmill pricing, this means that BPA consumers have already spent at least $5 billion on wind-energy production with no apparent return. By 2012, this potential wind capacity is likely to increase, costing BPA customers another $5 billion with no evident gain.
The basic line is that we have permitted policies to pass that are both financially and environmentally damaging. Wind developers would have lost their legally mandated status if these laws had not been in place, and there would be no windmills on grids with plenty of hydro.
Electricity generated by the wind is not free. The cost of fuel for any power plant is only a portion of the total cost to a consumer. The fact that the cost of the fuel is zero does not imply that the cost of the power generated is also zero.
This is comparable to how hydroelectricity is generated. Although the cost of water is zero, the cost of hydro-generated power is not. It comprises charges for operations and maintenance as well as the cost of constructing the hydroelectric dam.
The cost of fuel for a nuclear plant is not zero, although it is a minor part of the total cost of generation. It is unquestionably less than the cost of fuel in a natural gas plant, where the cost of fuel accounts for almost 80% of the generation cost.
Wind generating appears to be worth the fuel cost savings for power companies who utilize oil as a fuel.
Oil, on the other hand, is not widely used due to its high cost.
To summarize, there appears to be no economic basis for installing windmills unless there are no low-cost alternatives. This is especially true when windmills are installed on a grid with plenty of hydro, because there are no corresponding fuel savings.
Inputs:
- Installing a 2-MW wind turbine costs around $3.5 million.
- The cost of operating and maintaining a wind farm is around 20-25 percent of the total cost.
- Wind turbines have a maximum life expectancy of 20 years.
- The cost of gasoline is approximately $4 per thousand cubic feet.
- Oil is currently priced at $80 per barrel.
- 1 kWh of electricity requires around 7.7 cubic feet of natural gas (dividing the generation in Table 7.2a by the fuel consumption in Table 7.3a in these tables published by the U.S. Energy Information Administration ).
- One kWh of electricity requires 0.00175 barrels of oil (using the same tables as above).
Assumptions:
- A wind farm’s capacity factor is approximately 30%. (land based).
- For Hawaii, a greater capacity factor of 45 percent is estimated.
- A wind turbine has a 15-year average lifespan.
- The wind farm’s interest charges are overlooked.
- Transmission line costs are overlooked.
A barrel contains how many gallons of crude oil?
A normal barrel of crude oil in the United States comprises 42 gallons of crude oil, which yields approximately 44 gallons of petroleum products. Refinery gains result in an additional 6% of product, resulting in an additional 2 gallons of petroleum products. Refineries in the United States create about 19 gallons of gasoline and 10 gallons of diesel fuel from a barrel of crude oil, as seen in the graph below. The remaining one-third is made up of items like jet fuel and heating oil.
How much oil is required to manufacture a solar panel?
The answer is around a factor of 20 less than you believe. Sure, this might be beneficial to the global economy, but it would be detrimental to our wallets. Consider all the wonderful things you could do with an extra $360 billion per day.
Assume a high-efficiency conversion procedure for solar thermal plants (>50%) and a conversion efficiency of 42% for conventional natural gas power plants.
In that situation, it takes around 18kWhr from a barrel to create one kWh via PV (yes, considerably more than your normal estimate) and 30kWhr using CSP.
PV panels cover roughly 40 m2 and generate an average of 3kWh/m2 (with 2009 technology). Thus, 40 m2 x 3 = 120 Whr / 18kWhr = 7 panels are required to produce 1 kWh.
A 200-liter barrel holds 4728 liters (124.74 gallons) of liquid; if filled with oil, the barrel holds around 35 pounds or 15 quarts (little more than half a gallon) (this varies depending on distillation endpoints).
This indicates that 17,208,000 barrels of oil per day would be required to produce the same amount of energy as the current global power production (about 87 TWh/day) generated by solar panels.
Because the present global daily production is just 85 million barrels, it would take nearly three years of global oil production to produce enough solar panels to create the amount of electricity we currently use!
