renewable energy policy on the investment decisions of renewable electricity producers. We develop and solve a dynamic optimization model to understand how investment in wind energy depends on market and policy uncertainties. These uncertainties include the federal government's uncertain decision about the...
A reversible fuel cell combines two methods of energy production, uniting one of the previous fuel cell types with a solar or a wind generator. Like all other fuel, it produces energy and water vapor, but the water is then stored for later. During times of high wind or solar activity, t...
Wind is the flow of air in the atmosphere. Differences in air pressure cause the air to move from high pressure areas to low pressure areas. In a wind turbine, the wind is converted to 100 per cent renewable electricity. The wind turbines convert the wind's kinetic energy into electrical ...

This renewable resource relies on the natural heat stored within the Earth's crust, which can be accessed through geothermal power plants or geothermal heat pumps. Geothermal energy is a reliable and continuous source of electricity and heating, with minimal emissions and a small environmental footpr...
Using new intermittenttechnologies like solar and wind requires changes in grid management tomaintain a constant energy balance in real-time. This comment analyzesproposed solutions for the integration of renewable resources into the electricitygrid, and the legal and regulatory steps required to achieve...
When air moves quickly, that motion means kinetic energy, which can be captured. Learn how the simplest possible wind-energy turbine works.
Tidal wave energy is based on the power of the ocean. Ocean wave energy is a non-polluting, sustainable and renewable source of energy which is safe to use, but understanding how wave energy devices work is key to getting the most from this free and limitless resource. ...
The energy transition carries many benefits, including mitigating climate change, enhancing energy security, addressing resource depletion and meeting the growing energy demand. By shifting to renewable energy sources such as wind and solar, we can improve the resilience of our planet to climate change...
No matter the motivation to use green energy, renewable energy certificates are a way to prove and track how much renewable energy you use. Here's how to know when RECs are worth the investment.
