Modelling Approaches

This study reviews and describes some of the existing research and mechanisms of operation of organic photovoltaic (OPV) cells. Introduced first are problems that exist with traditional fossil fuels that result in most of the world energy challenges such as environmental pollution. This is followed by the description of baseline organic solar cell (OSC) structures and materials. Then, some of the existing modelling approaches that have implemented either a one- or a two-dimensional drift-diffusion model to examine OSC structures are reviewed, and their reproducibility is examined. Both experimental and modelling approaches reviewed are particularly important for more and better designed research to probe practical procedural problems associated with OSCs that hinder the commercialization of OPV technology.

World Energy Outlook

In this chapter, the correlation of growth in population, economic welfare, and increase in the energy demand is evaluated with examples. The biggest concern of mankind is which sources cover the immense energy demand. It is obvious that fossil fuels are the base energy source, and in order to supply developing energy needs, serious investments are needed in the energy sector. That is why the results of monetary aspects in energy prices and the conditions in leading supplier countries are also evaluated.

Co2 Emission Intensity

Measurement of the CO2 content of the atmosphere shows a constant increase over the last century connected to the increasing use of fossil fuels. In the light of the energy outlook of the World Energy Conference, we have tried to assess the evolution of CO2 emissions due to the use of fossil fuels, which in itself is the consequence of world economic development. We have thus defined the concept of CO2 emission intensity as the amount of CO2 involved in a one percent growth in world industrial production. Our estimate shows that in the middle of the next century CO2 emissions will reach a volume of several percent of the emissions of the CO2 flows caused by the leading atmosphere/ocean and atmosphere/ground physicochemical and biological balances. The reduction of these flows would require the replacement of fossil fuels and especially coal by nuclear energy or energy conservation of such an amplitude that it seems inaccessible. It thus seems indispensable to refine models capable of defining, with sufficient accuracy, the CO2 content of the atmosphere and to compare the basis of theories concerning the possible impact of this content on the temperature of the Earth.

Clean Energy Source

The world is constantly seeking new sources of energy to replace the use of coal and fossil fuels to generate electricity. And a strong source of energy from the ocean is one of the hopes of scientists around the world. Ocean energy is an endless renewable energy source for making electricity used for the world. Marine technology was once considered too expensive to be a viable source of alternative clean energy, especially compared to already developed products such as wind and solar. However, with the increased price of oil and the issues of global warming and national security, U.S. coastal sites are looking to add ocean energy to their renewable energy portfolios. This paper gives an overview of ocean energy technologies, focusing on two different types: wave, tidal. It outlines the operating principles, the status, and the efficiency and cost of generating energy associated with each technology.

The World

The world needs new, environmentally friendly, and renewable fuels to exchange for fossil fuels. The fuel must be made from cheap, abundant, and renewable resources. The research area of solar fuels aims to meet this demand. This paper discusses why we need a solar fuel, and proposes solar energy as the major renewable energy source to feed from. The scientific field concerning artificial photosynthesis is expanding rapidly and most of the different scientific visions for solar fuels are briefly reviewed. Research strategies for the development of artificial photosynthesis to produce solar fuels are overviewed, with some critical concepts discussed in closer detail.
