Hydropower, or hydroelectric power, is the most common and least expensive source of renewable electricity. Hydropower technologies have a long history of use because of their many benefits, including high availability and lack of emissions. Hydropower is fueled by water, so it is a clean fuel source. Hydropower technologies use flowing water to create energy …
Tides are the daily swells and sags of ocean waters relative to coastlines due to the gravitational pull of the moon and the sun. Although the moon is much smaller in mass than the sun, it exerts a larger gravitational force because of its relative proximity to earth. This force of attraction causes the oceans …
Wind energy technologies use the energy in the wind as the source for generating electricity, charging batteries, pumping water, grinding grain, and so on. Most wind energy technologies can be used as stand-alone applications, connected to a utility power grid. For utility-scale sources of wind energy, a large number of turbines are usually built close …
Solar energy technologies produce electricity from the energy of the sun. Small solar energy systems can provide electricity for homes, businesses, and remote power needs. Larger solar energy systems can produce more electricity and feed the electric power system. The block diagram of a solar energy system is shown in Figure 1. The system consists …
Biomass is an organic matter produced by plants, both grown on land (terristial biomass) and grown on water (aquatic biomass) and their derivatives and animal manure. The energy obtained from biomass is called the biomass energy. Biomass can be considered a form of solar energy as it is used indirectly to grow these plants by photosynthesis. …
The biogas plants are built in different sizes and shapes depending on the process carried out. These plants are mainly classified as: Continuous or batch type, Dome and drum type. Continuous or Batch Type Biogas Plants In the continuous type of biogas plant the biomass is fed regularly to the digester and it delivers the …
The biogas is produced by digestion, hydrolysis and hydro-gasification. The composition of biogas is as follows: The presence of CO2, in biogas reduces its octane rating. The octane rating of biogas is 110 with CO2. In case the CO2 is removed from the biogas (CH4) its octane rating increases to about 130 as against the …
Hi friends, In this article, I am going to discuss the MHD generator working principle. Also I will provide you some basic information about it. A Magneto Hydrodynamic Generator is a device which converts heat energy of a fuel directly into electrical energy without a conventional electric generator. This system eliminates all the …
Many homes in various nations are turning to power their homes with renewable energies. When you decide to go for off-grid or grid-connected power systems, you have two primary options for renewable energy equipment. These options include wind turbines and solar cells. So, which one is suitable and better for you? Wind energy or solar …
Hi friends, In this article I am discussing the OTEC working principle, types, advantages and disadvantages. You will find this article informative and interesting, I hope so. The oceans and rivers cover about 70% of the earth’s surface which receives, store and dissipates the vast amount of thermal energy. Thus they act as …
