Fog and mist often add to a photograph, giving it a softer, aesthetic look. Since fog and mist are generally a dawn phenomenon (water vapor condenses when temperature and dew point are within two or three degrees of each other) I got these shots early in the season since I live over an hour away from the field (I only had to get up at 4:30 to get these shots).
Since there is usually no wind associated with fog or mist, wind turbines are not likely to rotate, since they need at least a 4 MPH breeze. I was fortunate to have a view of some turbines on higher ground (where there was some wind) overlooking background mist on lower ground.
This past winter I began thinking about what might be an interesting local photographic project. Then, while on a trip through the countryside, I rediscovered wind turbines that I saw along the hilltops. So, I began exploring some of these fields from the surrounding roads. I will admit that my bias is towards renewable energy. I have no financial ties to any energy company (except for my monthly utility and gasoline bills). Rather, my bias results from data. Fossil fuels are not only warming the planet, but they will run out at current consumption levels over the next 50 to 100 years. The geological, climatic, and biological data (presented earlier on this website) all point to the critical importance of finding alternate energy sources.
Beginning in March I began photographing the turbines under different weather and lighting conditions and eventually got access to photograph some of the turbines up close. Contrary to what you might have heard, they
only make only a soft whirring sound. To my ear, it is almost as pleasant as listening to the surf. There are times, however, when some become noisy, producing whistling or other noxious sounds. This is due to rough surfaces developing on the leading edges of the blades from wear and tear, or small blade holes caused by lightning strikes. However, power companies replace the blades once noise becomes a nuisance. The turbines in this field (almost 100 of them) are certainly tall, standing 280 feet to the hubs with each blade extending out to 120 feet. And they are even taller in the west, some going 500 feet to the hub!
While I will grant you that wind turbines are not as aesthetic as trees and
flowering plants, they do present a majestic look over the landscape. Although many communities have rejected these (particularly when proposed for
offshore), they have a small footprint and have far more grace than traditional power plants. They take little time to erect and when finished the land is not compromised so crops or cattle can be farmed. Some folks almost have them in their back yards.
Wind turbines are not the total solution to our energy needs. There are several forms of renewable energy besides wind: solar, hydroelectric, biomass, hydrogen and fuel cells, geothermal, and tidal. Collectively, these sources will diversity our energy grid as the cost of these technologies decrease. This would have the added advantage of minimizing the risk of power plant shutdowns due to damage or maintenance.
I will present more photos and comments about wind turbines in future posts. I will add the best photos to my online gallery later and I anticipate a printed photo exhibition in the more distant future.
Do let me know your thoughts, positive or negative, on renewable energies.
You can learn more about wind turbines, including engineering information and references, from Wikipedia.
People love science when it treats their ills or results in a new iPhone. But when science brings our fundamental beliefs into question or threatens our comfortable way of living we revert to medieval thinking.
I am stretching things a bit because today’s post does not focus on the natural environment, rather one that is human-made. According to the “rules,” the harsh light of mid-day is the worst time to photograph. However, today’s unsettled weather found the sky filled with clouds moving at a good clip so I got my “Big Stopper” filter and went out to photograph Rochester’s iconic bridge, the Douglass-Anthony Memorial.
My camera set to ISO 100, lens @ 29mm, f/22 @ 30 secs., here it is:
As winter is simple, spring is complex as a variety of life re-emerges. Plants are budding, even though we had record lows and snow, earlier this month. Here are just a few photographs of what I found.
Winter is not the most popular time to photograph. Not only is it cold but everything is so drab. However, winter is a great time for us black and white photographers. So, I donned my winter gear and spent some time in the woods in late February looking for some good tree compositions to photograph after dark. My idea was to use my flash to highlight a particularly interesting tree so it would stand out against a relatively dark background, much as you might do in a studio with a black, felt background cloth.
Once finding the compositions, the trick was finding the same shooting spot after dark. Accomplishing that, I set my camera on a tripod; then using Kodak Tri-X 400 film I set my lens to f/2 and the shutter to bulb. While handholding my Speedlite flash off-center from my camera, I opened the shutter just long enough to manually trigger the flash. I took three shots of each composition at 1/1, 1/4, and 1/8 power. Twenty-seven frames later, here are the best (click to enlarge).
Located at the eastern end of Lake Erie, the Dunkirk power plant, built in 1950, now burns natural gas, though coal can still be used as a backup fuel. As you can see, the stacks no longer emit that dense smoke plume as in years past. Coal only produces about 1/2% of New York State’s power. In 1950, coal power generated nearly 46 percent of electricity in the country, making it the largest power source at the time, according to the Energy Information Administration. However, by 2017 natural gas had overtaken coal , generating about 34 percent of electricity compared to coal’s 30 percent.
Still, natural gas emits some particulates, along with carbon dioxide. While natural gas is a step forward, greenhouse gases will continue to raise global temperatures, most pronounced at the poles and in the seas, at an alarming rate. The computer models all show that the planet’s flora and fauna will be drastically affected by the end of the century. Many coastal cities will be partly under water, agricultural land will be displaced, and summer heat will become dangerously high.
Nova recently aired a two-hour special on climate change, showing each step of how scientists from a range of disciplines have demonstrated how the level of carbon dioxide (and other greenhouse gases such as methane and water vapor) have caused global temperature change over the past 800,000 years. Scientists have also documented the fossil fuel signature of modern carbon dioxide molecules, showing how they differ from those carbon dioxide molecules produced before the industrial revolution. This is the “smoking gun” proving not only that the global temperature is the hottest in 800,000 years, but that the warming climate is caused by human activity.
The documentary concludes with the political and economic realities, and the policy strategies needed to address this global threat. Addressing climate change is a formidable challenge not only because of politics and economics, but also because we not only have to stop emitting carbon dioxide, we have to go carbon negative to stop the steady increase of global temperatures.
This not only means producing nearly all of our power from renewable energy, it also means using far less power—leading us into what I call neo-industrialization. More on this in a future post.
Will we do it?
Even if you disagree with the findings of climate scientists, this Nova special is well worth watching. It is always useful to be familiar with one’s opponents’ arguments and evidence to know what one is refuting.
It really looks like the far North for a short while here on America’s north coast. Since fresh water begins to freeze at 32º F, you can get what looks a lot like Arctic ice, as shown in the first photo of Charlotte pier at the mouth of the Genesee River.
People love to build along the water, so clearly evident with the large estate in the second photo. Although the lake-level can be somewhat controlled via international agreement (see my earlier post about Great Lakes flooding) this house is vulnerable to flooding, due to changing climatic conditions. Nevertheless, it looks like a pretty nice place to be in June through September.
