The NBA season starts tonight, and much has happened since the end of the NBA Finals. The Eastern Conference has loaded up on top, with the Knicks and the 76ers making big moves over the summer to compete with the reigning champion Celtics. Over in the Western Conference there is as com...
Although it's not a perfect analogy, you can think of the Earth sort of like your car sitting out in a parking lot on a sunny day. You've probably noticed that your car is always much hotter inside than the outside temperature if it's been sitting there for a while. The sun's ra...
Wind turbines in Greece set a national record on September 6, accounting for 81 percent of the country's electricity output. High temperatures, wildfires and flooding pretty much sum up the weather patterns in Greece since the summer. From an unprecedented amount of rain in...
Otherwise, we will see those numbers much, much sooner," said Mills, in the news release. The results of the simulation highlights the already high temperatures the world is experiencing will increase even further, the study said, wi...
Most solar panels have cells that can convert 17-23% of the sunlight that hits them into usable solar energy. The efficiency depends on the type of cell in the panel. Monocrystalline cells are more efficient and generate more electricity, while polycrystalline cells tend to be more affordable....
Leachate can drain out of the landfill and contaminate groundwater supplies. Today, impermeable clay caps and plastic sheeting prevent much of this run off, making the landfills much safer than they were just a few decades ago. Still, any leachate is too much if it's draining into your ...
These layers work together to create solar energy in the form of electricity. When the sun’s light, full of tiny particles called photons, hits these layers, it causes a reaction that frees up electrons. These freed electrons create an electric current. The silicon layers of each solar ...

But if you keep track of all the tasks you’ve completed, you’ll have a much better idea of progression and how much closer you are moving towards your goals. On top of this, you’ll be reminded of how productive you have been, which will help in the long-term of keeping you ...
Designed to improve on the classic monocrystalline design, PERC photovoltaic panels possess apassivation layeron the rear surface of the cell. The passivated emitter and rear contact reflective layer enhance how much of the sun’s energy the panel can absorb at once. ...
