Secilia Peraza A renewable amine for photochemical reduction of CO2 Summary Photochemical reduction of CO2 to produce formic acid is high in demand for renewable energy sources that create energy to produce transportable fuel by photosynthesis Artificial photosynthesis is a step forward for chemists in the photochemical reduction of carbon dioxide. Nevertheless, an often-neglected necessary ingredient for photochemical CO2 reduction is a sacrificial electron donor, such as a tertiary amine…

1. INTRODUCTION The need for electrical energy and its global impact, ever since it’s being used is phenomenal. Hence, there is an immense pressure on all nation’s for ensuring electrical energy security. In this report, some key aspects of electrical energy statistics, both technical and economical are discussed and then compared between the United Kingdom** and Republic of India. 2. UNITED KINGDOM The United Kingdom is one among the large economies in the world and is also a “pioneer for…

Thermodynamics deals with the relationship between heat and mechanical energy. There are four laws of thermodynamics. Zeroth law of thermodynamics – If two thermodynamic systems are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.First law of thermodynamics – Energy can neither be created nor destroyed. It can only change forms. In any process, the total energy of the universe remains the same. For a thermodynamic cycle the net heat supplied to 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…

and China would just be wasting money and time on these clean energy sources, considering that this would not stop the problem of air pollution entirely. However, the excessive demand on a healthier environment is enough to want to bring somewhat of a positive change. It is not right to purely reject this alternative…

Wind With Solar Using Cuk and Sepic Converters This chapter presents a hybrid model of solar and wind energy. This gives the hybridization of wind with solar using the CUK and SEPIC converters. In this model the solar PV panel source is connected to the CUK converter and correspondingly the wind turbine source is given to the SEPIC converter. Solar energy and wind energy are the two renewable energy sources most common in use. Hybridizing solar and wind power sources provide a realistic form of…

good because we will get sun to keep the house warm in the and rain and sun for our garden. Energy What energy source will your house use and why? We will be using solar panels to control or energy sources. What energy conservation measures will your house use and why? We are going to put tinted windows to block the sun for the summer but probably replace them in the winter. Is this source renewable or…

Investor interest in the emerging global carbon credit market has created apt conditions for risk management products, ranging from insurance to derivatives. There is a growing recognition of carbon as a commodity that can be traded in spot market, and in the form of other complex financial products, such as derivatives and exchange-traded funds. Currently the carbon credit trade in Asia is dominated by China and India with carbon emissions trading showing the potential to become the world’s…

William Kamkwamba once said “If you want something, all you have to do is try.” William wanted to build a windmill so that he could create electricity and pump water, but that was not all his achievement. William left a legacy as The Wind Harnesser because he used what he had to save his country. William Kamkwamba changed the world as a boy architect who built a windmill to not only defeat starvation in Malawi, but to improve everyday life by providing the whole town with electricity. When…

a. Describe 5 major advantages associated with High Voltage Direct Current (HVDC) distribution systems when considered alongside alternative solutions. [5 marks] i) HVDC have lower losses when compared to the equivalent AC cable distribution. The DC power transmission lines run at losses of approximately 0.3-0.4% per 100km. Converter stations also need to be considered which have losses of around 0.6%. Overall HVDC transmission losses are nearly always lower than AC transmission. ii) HVDC…
