With its windy coasts, untapped rivers and huge tidal and wave resources, Alaska can quickly become a national leader in producing alternative energy. Although Alaska is the second-largest oil producing state in the country, the citizens have had to pay very high electricity bills recently; oil is no longer easily available … Continue reading
We mostly talk about solar panels that convert sunlight into electricity. But we can utilize sunlight by using another technology known as concentrating solar technology. In this technology reflective mirrors are used to concentrate light onto a liquid to make steam. This steam then converts energy into electricity with the … Continue reading
Hydro power is the term usually applied to the power/electricity created from the force of running water. It is generally less expensive than the mining of fossil fuels and does not contribute to greenhouse gases and climate change. Unlike other alternative energy sources like the sun or wind, water can be stored which … Continue reading
