Renewable energy production in Europe and Central Asia 2004 (heat production and electricity generation) Renewable energy production in Europe and Central Asia 2004 (heat production and electricity generation)
Hydropower, generation of electricity from dams in rivers, represents the majority of the energy produced, so far, with waste incineration - both from municipal and industrial sources, as a distant second. Other energy sources, such as biomass, windpower and solar power represents a very little share of the renewable energy produced so far. Energy consumption has been increasing in the region, since the 1990s, and with it the emissions of greenho...

From biomass to energy consumption From biomass to energy consumption
As biomass feedstocks are widely available, bioenergy offers an attractive complement to fossil fuels and thus has potential to alleviate concerns of a geopolitical and energy security nature. However, only a small part of globally available biomass can be exploited in an economically, environmentally and socially sustainable way.

Use of Renewable Fuels and Waste for Electricity Generation Use of Renewable Fuels and Waste for Electricity Generation
In 2007, 15.8% of the supply of primary energy in Latin America and the Caribbean came from renewable fuels and waste (solid and liquid biomass, biogas, and industrial and urban waste). This is higher than the worldwide average of 9.5% for the same year. Of the region’s countries, Haiti, Paraguay, Nicaragua and Guatemala each obtain more than 50% of their primary energy from renewable fuels and waste. It is important to note, however, that this f...

Energy intensity of economy: Percentage growth from 1980 Energy intensity of economy: Percentage growth from 1980
Emissions increase as economies and populations grow; however, there can also be an energy decoupling (relation between energy and GDP) and a decoupling of emissions and decarbonization (relation between emissions and energy consumption). In this way, an increase in per capita income is achieved with less energy consumption and reduced emissions (ECLAC, 2009). Examining an energy intensity index by region for 1980-2005, one sees that, in aggregat...

Energy intensity in Latin America and the Caribbean Energy intensity in Latin America and the Caribbean
Available evidence indicates that energy intensity – the ratio between energy consumption and gross domestic product (GDP), expressed in purchasing power parity (PPP) at 2005 prices – in Latin America and the Caribbean remained almost constant in the 1980-2007 period. This shows that the region has not made the progress necessary, in terms of energy efficiency, to reduce its emissions of greenhouse gasses. The stagnation in energy-intensity level...

Latin America greenhouse gas emitters by sector Latin America greenhouse gas emitters by sector
According to reports from the region’s countries, contained in national communications to the United Nations Framework Convention on Climate Change, the main sources of greenhouse gas emissions relate to changes in land use, forestry, agriculture and energy consumption. Brazil stands out as the highest emitter of greenhouse gasses caused by land use changes, accounting for more than 800,000 metric tons of CO2 equivalent. The importance of agricul...

Carbon intensity of energy use: Percentage growth from 1980 Carbon intensity of energy use: Percentage growth from 1980
By comparing the emissions:energy ratio (carbon intensity) between regions, one finds different patterns over time. Thus, between 1980 and 1995, decarbonization in Latin America and the Caribbean was in line with the world average; in the first half of the 1980s, the region progressed even faster than the OECD countries. Later, between 1995 and 2003, the emissions-to-energy consumption ratio increased.

Marginal abatement cost curve for Central America in 2030 Marginal abatement cost curve for Central America in 2030
Estimates of the marginal costs of emissions reduction for Central America show that decarbonization options should be directed towards energy efficiency in the residential and services sectors, mainly arising from savings due to reduced energy consumption. Similarly, the mitigation strategy should be focused towards reducing deforestation and degradation, with additional benefits for biodiversity and water supply. Sectors like transportation and...
