Human adult Daily energy intake as food: The Zap you get when walking across the room and touching a door frame is 20600 good example. Secondary Sources by conversion from Solar A. The value of a monopoly with minimum number of wires. Can clean up S, CO2, N2 more easily. If we use evaporative cooling how much water do need? About project SlidePlayer Terms of Service.

Need to control voltage, current, phase and frequency with changing loads and variations in generator output power to match generation to load. AC won out because of the better efficiency of AC power systems.

Thermal energy is created by combustion of fossil fuels coal, oil or natural gas combustion or by nuclear radiation. In a few places e. Most recently wind turbine designs harvest the energy in atmospheric winds and convert it into the force required to turn the magnets. Different generators have different ramp rates Coal fired plants may take a day or two build up from a cold start.

Control NOx with lowering temperature of the flame.


However, it is likely that the low priced coal in the US will be shipped overseas. These balance the loads and generation on an hourly and minute basis and set the whole sale price of power. Becquerel first demonstrated photovoltaic effect inbut the concept remained a novelty until when Bell labs engineers developed the first ecdn cell.

They are not designed for rapid cycling. Target is to control frequency to between These will become obvious as we delve into ecsn basics of electro-magnetism later on. The device generates electrical current when photons of energy from a light source e.

Feedback Privacy Policy Feedback. Allows for Independent power producers to connect to the utility owned grid so that they did not have to 22060 all there own power and back up.

Solar to Electrical by Thermal Electric Junctions 3. Provided incentive for energy efficiency, renewable energy sources and small gas fired turbines.

ECEN 2060 Lecture 2 August 28,2013 Frank Barnes.

We think you have liked this presentation. All of these systems require large capital investment in generation equipment and the distribution infrastructure required to deliver the energy from the generation site to the end users. Need to have it regulated to keep from bankrupting the users. Short term fluctuations are smoothed by inertia of the large machines. Many customers distributed so as to complement the day and night loading to pay the large capital costs.

Need for public investors for the large capital costs.


The voltage and frequency outputs change with the speed of the generator. Registration Forgot your password? Rankine Cycle includes Change of state from Vapor to fluid most coal plants 5.

Using the exhaust heat improves efficiency. This part of the course includes the following topics:.

ECEN Wind power systems

Act of for gas and electricity and also the security exchange commission. Political agenda in Wash D. Current reserves of Natural gas is 2. Finally, transformers on power poles or boxes deliver ac power to residential, industrial or commercial users at V. Hg with activated carbon, Particulates with electrostatic precipitator. In most of the developed world this infrastructure is in place. Opened the grid to more competitors of any size and using any fuel and to sell it anywhere. Photovoltaic power systems convert sunlight into electricity directly.

These do not operate transmission and distribution systems and do not have the same regulatory constraints. The economic drivers at the turn of the 20th century, coupled with the inherent advantages of distributed energy systems drove a rapid deployment of electric power, thus enabling an unprecedented growth in the economy and prosperity in the early part of the 20th century. His initial technical solution was based on Direct Current D. Also they only work when the sun is shining.
