Germany, Europe’s largest economy, is aiming to generate 65 percent of its energy from renewable sources by 2030. Additionally, Germany is currently in the process of abandoning nuclear power by 2022 and is making plans for a long-term exit from the use of coal. This change signifies progress for Europe as a whole. According to research from the Fraunhofer Organization of Applied Science, output of hydroelectric, solar, wind, and biomass generation units increased 4.3 percent last year, generating a total 219 terawatt hours (TWh) of electricity. The total national power production was 542 TWh. This national power production was derived … Continue reading →
High oil prices, competing demands between foods and other biofuel sources, and the world food crisis, have ignited interest in algaculture (farming of algae) for making vegetable oil, biodiesel, bioethanol, biogasoline, biomethanol, biobutanol and other biofuels. Algae can be efficienctly grown on land that is not suitable for agriculture and hold huge potential to provide a non-food, high-yield source of biodiesel, ethanol and hydrogen fuels. Several recent studies have pointed out that biofuel from microalgae has the potential to become a renewable, cost-effective alternative for fossil fuel with reduced impact on the environment and the world supply of staple foods, such as wheat, maize and sugar. What are Algae? Algae … Continue reading →
Several years ago, it was coal that brought a great deal of the progress needed in the rural areas. Much have changed over the years. With the advancement of energy technologies, going back to mining and processing coal no longer makes much sense. Politicians who promise to bring back coal-related jobs simply don’t have a grasp of reality. Advanced economies are already turning to renewable sources of energy and it makes sense for developing economies to do the same, unless they’re limited by urgency that they have nothing but cheaper fossil fuels to exploit. Of course, it’s not enough to … Continue reading →
Biomass is the material derived from plants that use sunlight to grow which include plant and animal material such as wood from forests, material left over from agricultural and forestry processes, and organic industrial, human and animal wastes. Biomass comes from a variety of sources including wood from natural forests, agricultural residues, agro-industrial wastes, animal manure, organic industrial wastes, municipal solid wastes, sewage sludge etc. When biomass is left lying around on the ground it breaks down over a long period of time, releasing carbon dioxide and its store of energy slowly. By burning biomass its store of energy is released … Continue reading →
Morocco, being the largest energy importer in North Africa, is making concerted efforts to reduce its reliance on imported fossil fuels. The country currently imports 95% of its energy needs which creates strong dependence on foreign energy imports. Renewable energy is an attractive proposition as Morocco has almost complete dependence on imported energy carriers. Morocco is already spending over US$3 billion a year on fuel and electricity imports and is experiencing power demand growth of 6.5 per cent a year. Morocco is investing heavily in the power sector by building new power plants such as expansion of coal power plant in JorfLasfer and establishment … Continue reading →
The continuous rise in fossil energy prices, combined with climate change concerns and progress in renewable energy sector, has catalyzed interest in clean energy systems across the MENA region, especially in the Mediterranean. The Mediterranean region has abundant renewable resources, such as wind, solar, and biomass, which makes it a fertile zone for renewable energy developments. The agricultural sector has played a key role in the progress of renewable energy sector around the world as it provides large areas where renewable energy projects are built and is also the predominant feedstock source for biomass energy projects. For example, agricultural sector … Continue reading →
Arab world is facing major sustainability challenges in achieving social, economic and environmental goals. Hydrogen economy can help Arab governments, companies, and citizens to save billions of dollars each year from reduced energy bills and sustainable waste management, while at the same time reducing carbon footprints – a win-win solution. Extremely arid climate, acute water scarcity, high energy consumption and polluting oil and gas industry present a unique challenge in Arab countries. Almost one-fifth of the Arab population is dependent on non-commercial fuels for different energy uses. All sectors of the economy — residential, commercial, transport, service and agriculture — demands … Continue reading →
Jordan has good biofuels production potential in the form of crop residues, agro-industrial wastes and urban wastes. Biomass energy sector in Jordan is slowly, but steadily, developing. As per a recent World Bank report, the country is currently generating 3.5MW of power from biomass resources which represent 0.1% of the total energy demand in the country. However there is no available data on the amount of biofuels produced in Jordan. Jordan produces significant amount of biofuel feedstock in the form of lignocellulosic biomass, used cooking oil, animal tallow, agro-industrial wastes, industrial effluents etc. In Jordan, transportation sector alone is responsible of 51% of final … Continue reading →
In an environment where the carbon footprint is becoming increasingly large, we need to start developing sustainable solutions which can keep greenhouse gases at bay. It is estimated that the building industry contributes to almost 40% of all of Australia’s greenhouse gas emissions! To put this into perspective, this consists to a whopping 90 megatons of emissions that are emitted annually in constructing new buildings and maintaining the infrastructure of pre-developed ones. It is time for us to take action! At Certified Energy, we believe in creating a sustainable future so that the building industry can thrive and support our … Continue reading →
The tremendous increase in the quantum and diversity of waste materials generated by human activities has focused the spotlight on waste management options. Waste generation rates are affected by standards of living, degree of industrialization and population density. Generally, the greater the economic prosperity and the higher percentage of urban population, the greater the amount of waste produced. A good example are the oil-rich GCC nations who are counted among the world's most prolific per capita waste generators. Reduction in the volume and mass of wastes is a crucial issue due to limited availability of final disposal sites in the … Continue reading →
Cement production in MENA region has almost tripled during the last 15 years, mainly on account of high population growth rate, rapid urbanization, increasing industrialization and large-scale infrastructural development. The growth of cement industry in MENA is marked by factors that are directly connected with sustainability, energy efficiency and raw material supply. Although the factors differ from country to country and cannot be generalized, there are major concerns regarding shortage of raw materials, GHG emissions, dependence on fossil fuels and lack of investment in technological innovations. For the MENA cement sector, key points for an environment-friendly industry are use of … Continue reading →
Combined Heat and Power (CHP), or Cogeneration, is the sequential or simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) in a single, integrated system. In conventional electricity generation systems, about 35% of the energy potential contained in the fuel is converted on average into electricity, whilst the rest is lost as waste heat. CHP systems uses both electricity and heat and therefore can achieve an efficiency of up to 90%, giving energy savings between 15-40% when compared with the separate production of electricity from conventional power stations and of heat from boilers. CHP systems consist of … Continue reading →
