How Much Oil Do Wind Turbines Use?

As the world seeks cleaner sources of electricity, renewable energy is heralded for not burning fossil fuels to produce energy. However, wind turbines contain moving parts and they require lubricants to operate at peak performance due to environmental and mechanical pressures. The amount of oil used by a wind turbine varies greatly depending on the size and type of turbine. A small turbine for powering the home only requires a very small amount of oil, whereas the largest offshore wind turbines regularly need topping up with large amounts of oil and other lubricants to keep them running efficiently. Proper maintenance including the use of oil ensures the reliability of cost-effective wind energy. As the fleet of wind turbines ages, many are entering a post-warranty period. This means that equipment repairs are becoming more costly for wind farm owners. Thus, proper maintenance including the use of oil to prevent equipment failure is critical to reduce costs and promote renewable energy production. Lubrication protects wind turbines from premature wear of many critical parts so they operate at maximum performance for greater productivity. Grease oil and grease are used in the gearbox, pitch gear, open gear, and yaw gear. Did you know every wind turbine contains 80 gallons of oil? At the moment, the average wind farm has 150 turbines. Each wind turbine requires 80 gallons of oil for lubrication, and this isn’t vegetable oil; this is a PAO synthetic oil based on crude… 12,000 gallons for one 150-turbine wind farm. Once a year, its oil must be replenished. To power a city the size of New York, it is estimated that about 3,800 turbines would be required… For just one city, that’s 304,000 gallons of refined oil. –Edward Rivis Wind Turbine Magazine and –Utility Smart * * *

Energy Poverty Kills

From Center for Industrial Progress by Alex Epstein Last week we looked at the need for a process of producing energy that is cheap, plentiful, and reliable—and we saw that solar and wind cannot produce cheap, reliable energy. How Germany embraced solar and wind and ended up in energy poverty Let’s take a look at this in practice. Germany is considered by some to be the best success story in the world of effective solar and wind use, and you’ll often hear that they get a large percentage of their energy from solar and wind. You can see here on this chart how this claim was made and why it’s not accurate. First of all, this is just a chart of electricity. Solar and wind are only producing electricity and half of Germany’s energy needs also include fuel and heating. So solar and wind never contribute half as much to Germany’s energy needs as this chart would imply. But that’s not the biggest problem. What you notice here is that there’s certain days and times where there are large spikes, but there are also periods where there’s relatively little. What that means is that you can’t rely on solar and wind ever. You always have to have an infrastructure that can produce all of your electricity independent of the solar and wind because you can always go a long period with very little solar and wind. So then why are the solar and wind necessary? Well, you could argue that they’re not and that adding them onto the grid will impose a lot of costs. In Germany, electricity prices have more than doubled since 2000 when solar and wind started receiving massive subsidies and favorable regulations, and their electricity prices are three to four times what we would pay in
