An introduction to renewable energy sources

An introduction to renewable energy sources In the presentation, an overview on renewable sources has been given. Energy is at the basis of human development. It is used in very different forms and comes from different sources. Most of them are directly, or indirectly, related to the Sun, which alone is the largest source of […]

Energy from the sun: an introduction to photovoltaics

Energy from the sun: an introduction to photovoltaics This presentation focuses on the exploitation of solar energy using photovoltaic devices. Solar energy can be converted in several ways. This lesson focuses on the conversion of light into electricity. This process is conducted with the support of solar cells. Solar cells are made of semiconducting materials […]

An overview of biofuels from biomass: technological options and legislation

An overview of biofuels from biomass: technological options and legislation In the presentation, an overview on biofuels and their production has been given. Moreover, the rules by the European Community have been reported. A biofuel is a fuel from biological materials, such as plants or animals. Biofuels can be divided into different “generations”. The first […]

Energy transformation: electricity generation and transmission

Michael W. Golay

Energy transformation: electricity generation and transmission This lesson focuses on electricity generation and electrical grid in our society, in particular on the renewable energy electricity generation technologies. Key questions that will be addressed include: why renewable energy is so important today; why the use of such technologies is not a straightforward and easy process compared […]

Technology innovation in the energy sector

Technology innovation in the energy sector The energy sector is the main responsible of greenhouse gas (GhG) emissions and is undergoing a deep change in its technology paradigm, both in industrialised and developing countries. The generating mix of the new power stations is more and more oriented to renewable sources as long as their costs […]

Energy costs and prices: renewables and electricity generation

Richard Schmalensee

Energy costs and prices: renewables and electricity generation Electricity generation refers to the process of generating electric power from other sources of primary energy. This lesson provides an overview on this issue with a particular focus on renewables. The main problem of electric power systems is the store of electricity. In electrical power generation, the […]

FOCUS – Prospect of geothermal energy exploitation in Croatia

FOCUS – Prospect of geothermal energy exploitation in Croatia Over the last few years in Croatia several international companies and local developers have worked on the potential of high enthalpy geothermal fields. They have managed to get several new exploration licenses for power generation from deep geothermal energy. The object interest is fractured carbonate geothermal […]

FOCUS – Renewable sources of energy

FOCUS – Renewable sources of energy When Croatia signed the Kyoto protocol agreement, it stated that Croatia will have to reduce its carbon dioxide emissions, implement programs of energy sufficiency or rational use of energy, diversify its energetic resources etc. In the time period from 2008 till 2012, Croatia fulfilled its Kyoto protocol demands (5% […]

Energy, growth and development

Energy, growth and development The lesson aims at analysing energy in terms of growth and development, focusing in particular on how society uses energy and how access to energy is distributed in the world. As nowadays not all members of society have same access to energy and technologies, limited access to energy and technologies translates […]
