Whether you’re growing vivid flowers, delicious veggies, or landscape shrubs, large-scale greenhouses need proper lighting. Greenhouses take up quite a bit of space and require adequate lighting for plants to grow.
Plants require sunlight, but LED grow lights can provide substitute lighting to help them grow. Unlike natural sunlight, greenhouse lights stay consistent during cloudy or winter weather. But producing light requires energy which in turn leads to carbon dioxide emissions, which isn’t great for the environment.
Going green (no pun intended) with greenhouse LED lights provides more benefits other than saving the environment. The most striking advantages for farmers came from energy and money savings.
Cost is always a major factor when it comes to energy and lighting. In the past, LEDs had high up-front costs. However, advancements in LED tech lowered costs to below most traditional bulbs. In the long run, greenhouse LED lights result in lower energy costs.
The Department of Energy states, “If all indoor horticultural lighting today was converted to LED technology, annual horticultural lighting consumption would be reduced to 6.3 TWh (terawatt hours) of site electricity, […] which represents lighting energy savings of 34% or $350 million.”
|Department of Energy U.S. 2019 Statistics|
|Cost per kWh (commercial)||$0.11|
|Approximate horticultural lighting cost||$1.056 billion|
|Terawatthours with all LED||6.3 TWh|
|Savings after LED||$350 million|
|Cost after LED||$650 million|
Roughly 30% in savings is quite significant. If your annual energy costs run up to $100,000 you would get another $30,000 back in your pocket with greenhouse LED lights.
The money farmers save in energy can turn to lower product prices for customers. That would allow the customers to purchase more quantity or more frequently, resulting in repeat business and happy customers.
As a greenhouse owner, you enjoy seeing your customers happy as a result. And you can be happy from all the savings. Never stop saving, by converting your greenhouse lights to LED.
