US Reports 'Unprecedented' Success With Methane Hydrate U.S. Geological Survey Scientists have been studying methane hydrates for years, including this drill used to estimate how much there might be under the Arctic permafrost. Could the future of cleaner fossil fuel really be frozen crystals now trapped in ocean sediments and under permafrost? US Reports 'Unprecedented' Success With Methane Hydrate

DOE - Fossil Energy: How Fossil Fuels Were Formed DOE - Fossil Energy: How Fossil Fuels Were Formed Contrary to what many people believe, fossil fuels are not the remains of dead dinosaurs. In fact, most of the fossil fuels we find today were formed millions of years before the first dinosaurs. Fossil fuels, however, were once alive! They were formed from prehistoric plants and animals that lived hundreds of millions of years ago. Think about what the Earth must have looked like 300 million years or so ago. The land masses we live on today were just forming.
Solar cells can be used in devices such as this portable monocrystalline solar charger. A monocrystalline solar cell A solar cell (also called a photovoltaic cell) is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. It is a form of photoelectric cell (in that its electrical characteristics—e.g. current, voltage, or resistance—vary when light is incident upon it) which, when exposed to light, can generate and support an electric current without being attached to any external voltage source, but do require an external load for power consumption.

Solar Panel Comparison, Most Efficient Solar Panels Where to Get Solar Panels Solar panels are the future and there’s no better time to get solar panels installed on your home or building. The founder of PayPal, SpaceX, and Tesla Motors, Elon Musk, is confident that “solar will beat everything, hands down, including natural gas.” The only question now is, “where can I get solar panels for myself?” The answer is simply to contact a handful of solar installers in your area and pick the one you trust most. The problem is, how do you know if the installer is good or not? Solar Panel Comparison, Most Efficient Solar Panels
A clean energy revolution is taking place across America, underscored by the steady expansion of the U.S. renewable energy sector. The clean energy industry generates hundreds of billions in economic activity, and is expected to continue to grow rapidly in the coming years. There is tremendous economic opportunity for the countries that invent, manufacture and export clean energy technologies. Responsible development of all of America’s rich energy resources -- including solar, wind, geothermal, bioenergy and water -- is an important part of President Obama’s Climate Action Plan and will help ensure America’s continued leadership in clean energy. Moving forward, the Energy Department will continue to drive strategic investments in the transition to a cleaner, domestic and more secure energy future. Renewable Energy Renewable Energy
So just how do we get electricity from water? Actually, hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller-like piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity.

How Do Wind Turbines Work How Do Wind Turbines Work Have you ever wondered how wind turbines actually work? In this article we aim to explain the process that enables these devices to convert wind energy into useable electricity. Wind turbines work in essentially the same way as an electric fan, however instead of using electricity to turn a fan which will create a gust, we are using wind energy (the gust) to turn a fan that will create electricity. The Inside of a Wind Turbine As you can see above, a wind turbine features a large compartment that the blades are attached to via a rotary device. This rotary device is often connected to a pitch system that is able to point the entire blade system either upwards or downwards in order to be more efficient during different wind patterns.

The Energy Story - Introduction Energy is one of the most fundamental parts of our universe. We use energy to do work. Energy lights our cities. Energy powers our vehicles, trains, planes and rockets. The Energy Story - Introduction
As we learned in Chapter 2, electricity flows through wires to light our lamps, run TVs, computers and all other electrical appliances. But where does the electricity come from? In this chapter, we'll learn how electricity is generated in a power plant. In the next few chapters, we'll learn about the various resources that are used to make the heat to produce electricity. The Energy Story - Chapter 6: Turbines, Generators and Power Plants
Power Plants Electricity is actually the flow or movement of electrons through a material. Electric generating plants typically produce electricity using magnetic conduction. This happens when a large number of conductive wires are spun around inside a magnetic field, causing electrons to move (i.e., electricity to flow). In a generating plant, the potential energy of various types of fuels (fossil, nuclear, or renewable) is converted into another form of energy (usually mechanical or heat energy). This energy is used to turn fan-like blades inside a turbine. These blades are attached to a pole-like shaft.

Institute for Energy Research | Fossil Fuels The Institute for Energy Research conducts in-depth economic and policy research on energy and environmental issues. The follow studies provide an extensive analysis of fossil fuels as an energy resource, their impact on markets, and their importance in energy policy debates. Below these studies is an in-depth overview of fossil fuels. Fossil fuels—coal, petroleum (oil), and natural gas — are concentrated organic compounds found in the Earth’s crust. They are created from the remains of plants and animals that lived millions of years ago in the form of concentrated biomass. According to the US Energy Information Administration (EIA), fossil fuels meet around 82 percent [i] of U.S. energy demand.

Science and technology for a clean energy future Enabling basic research is needed to underpin critical breakthroughs that can fundamentally alter energy systems, at large scale, several decades into the future, and to accelerate the implied transformations. Such pre-competitive research has a time scale well suited to the university environment, both because its impact is often beyond the time horizon for individual firms and because it prepares future leaders of forefront research. Many of the expressed faculty interests fall in this part of the portfolio: Renewable energy sources (wind, solar, geothermal, waves, biofuels),Electrochemical energy storage and conversion,Core enabling science and technology (e.g., superconducting and cryogenic components, nanotechnology and materials, Transport phenomena); andNuclear fusion.
