In 2015, global investment in renewables grew about 5 percent relative to the previous year and reached an all-time high of US$ 286 billion (bn). And there are more interesting trends: Investment in renewables’ based electricity generation capacity in 2015 has been more than double the investment in the major fossil fuels (renewables: US$ 266 bn versus US$ 130 bn for coal and gas stations). This also leads to added capacity in terms of Gigawatts in 2015 in renewables (134 GW) outstripping all other technologies combined (conventional coal, gas, and nuclear).

Generating electric power based on geothermal energy is attractive (i) because of the low CO2 emissions and (ii) because electricity can be produced constantly, independent of the availability of wind or sunlight. These characteristics make geothermal energy an important option for safe, cost-effective and climate friendly power production. The main caveats are that geothermal energy is not available everywhere and that it is uncertain whether the resource will actually be found at a given site.

The demand for energy across the globe continues to grow. Cities account for approximately two thirds of energy consumed worldwide and 70 % of the greenhouse gas emissions related to people. Energy prices have experienced nothing but growth for years now. Even in places where prices for electricity and heating appear low from a customer standpoint, subsidies actually end up footing the bill in many cases, which are in turn covered by national budgets that are funded by tax payers.

Over the last several years, municipal energy and climate protection management has become a central working area within German development cooperation. Municipalities are faced with immense and multi-faceted challenges: increased spending on energy is a strain on the inhabitants as well as public budgets. As a result, many municipalities are witnessing growing engagement in the area of climate protection.

In public buildings lighting accounts for about 40% of the electricity costs. If you multiply this figure by the number of kindergartens, schools and universities, town halls, local government buildings and government departments, libraries, swimming pools and hospitals, then the total is enormous. Lighting in public buildings is currently consuming far more energy than necessary, with all the negative side-effects such as high running costs, electricity bottlenecks and damage to the climate. That can easily be changed.

This report studies the development of criteria for assessing the compatibility of financial investments with the international goal to limit global temperature increase to below 2°C above pre-industrial levels. The findings are intended as a starting point and a key input for a longer term process to develop consensus-based 2°C investing criteria. The focus here is placed on investments in projects and physical assets, in particular of development and climate finance organisations.

The transition from fossil fuels to cleaner, safer energy technologies is under way. To pinpoint where decarbonization is happening most rapidly—and to extract lessons and best practices that can be applied to other areas of the global economy where progress is needed in the fight against climate change—this study by ClimateWorks, NewClimate Institute, Ecofys, and Climate Analytics compares past projections with actual developments in renewable energy, coal consumption, and passenger vehicles. Key findings include: Decarbonization of the power sector is happening faster than predicted.

A highly efficient use of energy is thus fundamental to limit GHG emissions. Yet, energy efficiency receives much less attention than the decarbonization of the energy supply.

Effective responses to climate change require efforts by both the public and private sectors to develop and disseminate new environmentally sound technologies (ESTs) on a global scale, as well as to adapt them to local needs. However, due to a number of market failures and specific uncertainties, the spread of green technologies is less than optimal, which necessitates additional incentives. Based on a review of recent literature, the present Global Challenges

Carbon dioxide emissions from anthropic activities have accumulated in the atmosphere in excess of 800 Gigatons since preindustrial times, and are continuously increasing. Among other strategies, CO2 capture and storage is one option to mitigate the emissions from large point sources. In addition, carbon dioxide extraction from ambient air is assessed to reduce the atmospheric concentration of CO2. Both direct and indirect (through photosynthesis) pathways are possible.
