pt-logo Português logo-esp Español

The first urban waste-burning plant for electric power generation is expected to begin construction in the first quarter of 2017, in the city of Barueri, in the state of São Paulo. The project with the name Energy Recovery Unit (ERU) follows the same model of power plants in countries such as Sweden, Norway, the Netherlands and Germany.

In the model installed in Barueri the solid waste is burned with a technique called Mass Burn, that is, it does not require any previous treatment or separation. These solid wastes combust, generating steam that moves turbines in the same way a thermoelectric plant would do. Some of the electricity generated is used by the plant itself, while 87% go directly to the city’s energy grid. In English, this type of energy generation is called Waste to Energy (WTE).

pt-logo Português logo-esp Español

According to the Bem Paraná Portal, “the most populous country in the world and also the largest emitter of greenhouse gases, China is investing heavily in energy infrastructure for the production of renewable energy. noticia_483104_img1_eolica1According to the agency, hydropower and wind power generation are expected to concentrate most of the investment, with short-term targets set for measures to be in place by 2020 “In addition to the environmental impact of replacing fossil fuels with renewable sources, the policy should also generate 300,000 direct and indirect jobs only with respect to wind energy.”

To learn more about the case of the change in the energy matrix, we recommend reading the article by Ming et al. (2014). In the article published in Renewable and Sustainable Energy Reviews (Elsevier) entitled “Review of renewable energy investment and financing in China: Status, mode, issues and countermeasures”


1-s2-0-s1364032113007752-gr1With the support of national policies, China’s renewable energy generation industry has experienced a rapid development period and entered the world forefront level, especially in the aspects of installed capacity and speed of newly installed capacity. However, with the rapid development of renewable energy, the power generation industry is facing more and more challenges, particularly in investment and financing. For wind power industry, there are also some problems such as single financing channels, blindness of investment projects and so on, which will result in financing difficulties for some advanced projects. In addition, the problems of photovoltaic (PV) power generation lead to vicious competition and to tumble in international market, thus the overcapacity of China’s entire PV industry emerges. Generally speaking, the renewable energy industry is facing a seemingly contradictory prediction of funding deficiencies and blind investment, which is derived from the government-centered renewable energy investment and financing. This government-centered mode has promoted the development of renewable energy industry in the early stage, but it can not be adapted to the requirements of sustainable development. In view of these, the problems of renewable energy investment and financing are thoroughly studied in this paper.

This paper proceeds as follows: Firstly, the overview of the development of China’s renewable energy industry is briefly introduced. Secondly, the status quo of China’s renewable energy investment and financing is explored in detail based on the following five perspectives: investment situation; Investment and financing bodies; Investment and financing means; Sources of funding and financing channels.1-s2-0-s1364032113007752-gr21Secondly, the patterns and characteristics of renewable energy financing are summarized and a comparative analysis of wind power and photovoltaic power generation is carried out. Finally, renewable energy investment and financing issues are discussed and further feasible proposals are put forward. In all, this paper is of great significance in the sustainable and healthy development of China’s renewable energy.

After COP22, Morocco To Implement 100% Renewable Electricity

pt-logo Português logo-esp Español

At COP22 the global community came together to discuss, among others, how to move more quickly to more sustainable energy supplies. This transition must be understood as a source of innovation and a driver of change towards an economic system that works within the Earth’s limits. Morocco has pointed out some of those gains successfully, but there is still a long way to go to changing its energy patterns. Read CleanTecnica’s report about the COP’s host country Morocco’s challenges in this process.

At COP22, 48 countries committed to “strive to meet 100% domestic renewable energy production as rapidly as possible while working to end energy poverty, protect water and food security, taking into consideration national circumstances.” They are among the most vulnerable countries and are united as the Climate Vulnerable Forum (CVF). With their declaration, these countries prove unique leadership in Marrakesh, keeping up to the promise to make the first COP after the Paris Agreement entering into force, an “Action COP.”

Changes in the energy sector imply changes to the whole economy and thus need thorrow planning and integration between science and technology, the economy, the political process and the cultural sphere as well.

From garbage to electricity: São Paulo gets the largest green thermal plant in Latin America

Example of use of garbage for power generation, a biogas-powered landfill plant has the capacity to provide electricity to a city of up to 300,000 inhabitants.

img_20151118_151349150Project that turns methane gas from waste into electricity cost US $ 100 million. | With the potential to generate 29.5 megawatts (MW) of clean energy from urban waste, the largest biogas plant in Latin America was recently inaugurated in the Greater São Paulo region. The Termoverde, installed in the landfill of the municipality of Caieiras, produces energy from methane and emerges as an important energetic reinforcement for the region. The total cost of the project was R $ 100 million.

Built by the Solví Group in an area of 15 thousand m², the thermoelectric generates 26 MW per hour, enough energy to supply a city of 300 thousand inhabitants. The facility began to be built in 2014 and obtained authorization from the National Electric Energy Agency (ANEEL) to start operations in July this year.


According to Carlos Bezerra, director of Termoverde Caieiras, the implementation of the biogas plant was only possible thanks to some incentives
Governmental organizations that made the project viable. “The discount of the Tariff for the Use of Electric Distribution Systems (TUSD) by ANEEL; The exemption of PIS / COFINS /ra/pequena/Pub/GP/p4/2016/10/31/Economia/Imagens/Futuro/aereaB.jpg by the federal government and ICMS by the state government made possible the installation. But it’s still little. An adequate public policy to encourage renewable energy is needed to have more power plants like these. ”

Bioethanol expansion and its consequences

pt-logo Português

The journal Tropical Conservation Science in a study investigates the effects of the expansion of sugarcane production for export and what are the measures to diminish the effects on the ecosystem of the Atlantic Forest.

Bernard, E., Melo, F. P. L. and Pinto, S. R. R. 2011. Challenges and opportunities for biodiversity conservation in the Atlantic Forest in the face of bioethanol expansion. Tropical Conservation Science Vol. 4 (3): 267-275. Available online: or directly here.

Brazil is the world’s largest producer of ethanol from sugarcane, an alternative to gasoline. Large companies, including international oil companies, are aware of the potential of Brazilian ethanol and are investing in the production and expansion of the country’s sugarcane plantations. The growth of the ethanol market and the fulfillment of its demand impose some conservationist challenges to Brazil. The market points to the expansion of the area planted with sugarcane, but this could be extremely detrimental to the conservation of the rest of the biodiversity of the Brazilian Atlantic Forest. The impact of this expansion will be even more severe in the states of Alagoas, Pernambuco, Paraíba and Rio Grande do Norte, the country’s second largest sugar and ethanol producing region, and one of the most threatened portions of the world’s tropical forests (only 12% , ~ 1% legally protected), with most of the forest fragments smaller than 100 ha and several endemic species in the imminence of extinction. We argue here that instead of expanding the planted area, increased productivity should be the most logical and environmentally sound solution for the region. Furthermore, we indicate that the current challenge is to increase the number of sugar-alcohol companies that adopt best environmental management practices and turn these programs into real opportunities for the restoration of biodiversity and environmental services in an ecosystem in imminent collapse. We strongly recommend that sugarcane mills should take a step further and at least ensure the protection of the remaining habitats beyond what is established by current environmental legislation.
