Energy economics

Historically the humanity has been conditioned to use fossil fuels and its derivatives, but the finitude of this natural resources incentive the development of new types of energy, mainly the renewable ones. In addition, the overwhelming of the atmosphere with carbon dioxide makes this new kind of energy a new hope because is commonly seen as the solution to the environmental problems. As a result, the benefits are considered the only point of view in many discussions about the theme, even though the drawbacks are significant and can be a barrier in the development of some energies like the solar. The benefits of the solar energy are commonly related to the natural resource characteristics, like the abundance and renewable capacity, which distinguish it from the traditional way of collecting energy. It is a common knowledge that Sun doesn’t stop shining, at least for more billion years, which means that the natural resource is not limitable like coal, nuclear energy and also the mineral gas. Also, according to the report of U.S. Department of Energy (2015), “The sun deposits 120,000 TW of radiation on the surface of the Earth, far exceeding human needs even in the most aggressive energy demand scenarios” which illustrates that the potential of this energy is immense if there is the ability to absorb it. On…

Timmons, D. (2015). The Economics of Renewable Energy. Global Development And Environment Institute, 1-35. The article explores the possible replacements of the ever diminishing supplies of fossil fuels. It views the prospects of using fossil fuels in the future as reducing every day given that they are created over geological time. It explores the probable sources of energy to replace the fossil fuels and recommends a number of alternatives that include wind power, solar, geothermal, nuclear,…

they obtain (“Occupation”). As soon as I finished high school, I was interested in studying Chemistry; I wanted to research and experiment. Then, it was when I learned about the engineering field and started to feel appealed by it. Between all specializations that the chemical engineering program has, I believe that the development of new types of energies and the development of polymers are the most interesting fields of the major. On the one hand, the rise of new types of energies is crucial…

Alphabet Energy Matt Scullin is the PhD student in UC Berkeley and he has high interests in thermoelectric technology. In his academic career, he found that the traditional way of power generating wastes about 60% energy. While with the thermoelectric technology people can generate electricity from wasted heat and it can improve efficiency in 10% to 25%. By using his own technology, Matt started a company called alphabet energy and producing superior thermoelectric device. He narrowed his…

Geothermal energy is one of the oldest sources of energy. (Geo) a Latin root meaning earth and (thermo) a Greek root meaning heat, is where the word originates from. A simple way to phrase it would be that you are using renewable, heat energy from the earth. So what exactly does it do? According to an article by Alternative Energy Some forms of geothermal energy heats up groundwater. This heat eventually generates to hot spots surfacing near the surface of the crust. Examples of these hot…

Thermal energy strorage Thermal Energy Storage is the temporary storage of high or low temperature energy for later use, bridging the gap between requirement and energy use. The storage cycle might be daily, weekly or seasonal depending on the system design requirements, and whilst the output will always be thermal, the input may be thermal or electrical. Principle 1) Sensible Heat Storage Heating a liquid or solid, without changing the phase: This method is called sensible heat storage.…

1.1 Power Flow Theory Power, as we know, consists of two components, active and reactive power. The total sum of active and reactive power is called as apparent power. 1.1.1 Active Power “Power is a measure of energy per unit time. Power therefore gives the rate of energy consumption or production. The units for power are generally watts (W). For example, the watt rating of an appliance gives the rate at which it uses energy. The total amount of energy consumed by this appliance is the wattage…

Introduction Thermodynamics is the study of heat and chemical transformations as a result of energy changes, energy is what keeps things moving in our everyday life and is applied to nearly everything to a point where knowledge of thermodynamics is common sense weather we know it or not. Now a days every household, car, office and even laptops and electronics have air conditioning which has allowed for appealing aspects of commercial use and consumer consumption, but what we don 't consider is…

GEOTHERMAL ENERGY 1.1 INTRODUCTION AND DEFINITION Geothermal energy is the utilization of heat present in the deep earth for the purpose of power generation or other direct use application. In general terms, geothermal energy consists of the thermal energy present in the Earth’s crust. Thermal energy in the earth is distributed between the constituent host rock and the natural fluid that is contained in its fractures and pores at temperatures above ambient levels. Globally, the most commonly…
