Renewable energy
Energy collected from renewable resources Globally there are over 10 million jobs associated with the renewable energy industries, with solar photovoltaics being the largest renewable employer.[13] Renewable energy systems are rapidly becoming more efficient and cheaper and their share of total energy consumption is increasing,[14] with a large majority of worldwide newly installed electricity capacity being renewable.[15] In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity.[16] Many nations around the world already have renewable energy contributing more than 20% of their total energy supply, with some generating over half their electricity from renewables.[17] A few countries generate all their electricity using renewable energy.[18] National renewable energy markets are projected to continue to grow strongly in the 2020s and beyond.

Renewable Energy Is Key to Fighting Climate Change Renewable energy is one of the most effective tools we have in the fight against climate change, and there is every reason to believe it will succeed. A recent New York Times column seems to imply that renewable energy investments set back efforts to address climate change—nothing could be further from the truth. What’s more, renewable technologies can increasingly save customers money as they displace emissions from fossil fuels. Wind and solar energy have experienced remarkable growth and huge cost improvements over the past decade with no signs of slowing down. In fact, the investment firm Lazard estimates that the cost of generating electricity from wind and solar has declined by 58 percent and 78 percent, respectively, since 2009. In the longer term, the U.S. The benefits are huge In addition to the climate benefits that they will help deliver, renewables already provide a wide range of market and public health benefits that far outweigh their costs. Change is here

Green Mountain Energy Company: A Leader in Renewable Power 40 Facts About Solar Energy - Conserve Energy Future The consumption of non-renewable sources like oil, gas and coal is increasing at an alarming rate. The time has finally come to look after some other renewable sources of energy i.e. solar, wind and geothermal energy. Although many countries have started utilizing solar energy extensively but still they have to go a long way to exploit this energy to fulfill their daily demand for energy. Here are few facts on solar energy that can help you assess the potential of solar energy to meet global requirements. What is Solar Energy? Solar energy refers to energy from the sun. The main benefit of solar energy is that it does not produce any pollutants and is one of the cleanest source of energy. Below are 40 Facts on Solar Energy Fact 1: Solar energy is a completely free source of energy and it is found in abundance. Fact 3: The solar technology can be distinguished into active and passive. Fact 4: The earth gets 174 Petawatts of incoming solar radiation in the upper atmosphere. Rinkesh

IEA: Renewable electricity set to grow 40% globally by 2022 | Carbon Brief The world’s renewable electricity capacity is set to rise sharply over the next five years, the International Energy Agency (IEA) says, expanding 43% on today’s levels. The forecast – a significant upwards revision of the IEA’s renewables projections last year – is largely driven by increasing expansion of solar energy in China and India, says the Paris-based organisation. The global dynamics of renewables expansion will also shift over this five-year period, with capacity growth in India overtaking that of the EU for the first time. Renewables accounted for almost two-thirds of net capacity additions in 2016, with almost 165 gigawatts (GW) coming online, the IEA adds. A further 920GW of renewable capacity will be installed by 2022, according to its forecasts. Carbon Brief breaks down the IEA’s numbers for 2016 and the main elements of its renewables forecasts for the next five years.

Énergie éolienne : fonctionnement, avantages, chiffres clés et enjeux Ce sont la Chine et les États-Unis qui disposent des plus grands parcs éoliens dans le monde, avec respectivement 229,6 GW et 105,4 GW installés à fin 2019(1). Suit ensuit l'Allemagne, leader européen de l'éolien (et mondial jusqu'en 2009) avec 53,9 GW installés. Si on rapporte les capacités éoliennes à la superficie et la population des principaux pays développant cette filière, le Danemark figure en revanche à la première place. En France En 2023, l’éolien a compté pour 10,3% de la production électrique en France métropolitaine selon RTE, consolidant ainsi sa place de principale filière renouvelable après l’hydroélectricité. En 2019, la puissance du parc éolien raccordé en France métropolitaine a augmenté de 1 361 MW pour atteindre près de 16,5 GW en fin d’année (+ 9% par rapport à fin 2018). En 2019, le parc éolien de la France métropolitaine a produit 34,1 TWh selon RTE, soit 21,2% de plus qu'en 2018. En Europe Au niveau mondial

Climate change: ISU working to fill gaps in diversity, inclusion | Local Education NORMAL — An initiative to improve diversity and inclusion at Illinois State University has mostly taken baby steps that might not be obvious to many. For example, more than 20 all-gender restrooms have been added to campus. Education about respect and building a sense of community have been added to Preview sessions for incoming students. Training for search committees includes suggestions for increasing the diversity of candidate pools. The accomplishments of women on the faculty and staff are being given more attention in university publications. NORMAL — Work is expected to begin in the 2018-19 academic year to identify what form a multicultural center might take at Illinois State University. But another step — creation of a website listing the implementation team's “action items” to address short- and long-term ideas — is intended to make sure the Campus Climate Task Force report does more than gather dust on a shelf. “Everybody has something to contribute,” she said.

California solar panels | guide to solar incentives, costs and savings in CA !! What solar incentives and tax credits are available in California? The main incentives to install solar in California is the 30% federal solar tax credit and the net metering law. The upfront utility based incentives from each of the main publically owned utilities are now exhausted for residential customers and almost exhausted for commercial customers. However, the investment case for buying solar panels for your home has never been stronger because reductions in the price of solar systems has more than compensated for the loss of some upfront rebates. Net Metering in California The California Public Utility Commission voted by a narrow majority of 3 to 2 to extend the ability of residential energy customers in California to be credited with full retail rates for excess solar power that they generate and feed back into the grid at times when the electrical loads in their house are less than their solar production. This is a very generous incentive and should not be taken for granted.

Renewable Energy Ready Homes (RERH) | ENERGY STAR The RERH Specifications were developed by the U.S. Environmental Protection Agency (EPA) to educate builders on how to assess and equip new homes with a set of features that make it easier and less expensive for homeowners to install solar energy systems after the home is constructed. The RERH specification and checklist takes a builder and a project design team through the necessary steps of assessing the home's solar resource potential and outfitting a home with the necessary minimum structural and system components needed to support a complete renewable energy system. Meeting the recommended elements of the RERH specification may not be possible in all home building situations due to factors such as excessive shading on the proposed array location. Solar Photovoltaic (PV) RERH Specification (4.82MB) details the site assessment and structural and system components needed to make a home solar PV ready. PV RERH checklist (134KB) includes a standalone copy of the RERH Solar PV checklist.

Hydroélectricité : définition, fonctionnement, chiffres clés, acteurs En France En France, de nombreuses centrales hydrauliques ont déjà été installées dans les sites les plus favorables (cours d’eau, massif montagneux, faible densité urbaine, etc.). Il y a environ 450 « grands » barrages en France selon la définition internationale de la Commission Internationale des Grands Barrages (barrages d’une hauteur supérieure à 15 mètres). Près de 220 de ces barrages sont utilisés pour produire de l’électricité, essentiellement dans les zones de montagne. Plus de 45% du parc national est situé en région Auvergne-Rhône-Alpes. La puissance totale des installations en France continentale avoisine 25,5 GW. Les autres barrages servent à l’alimentation en eau des villes, à l’irrigation (essentiellement dans le sud de la France), à la protection contre les crues, et pour les anciens barrages à l’alimentation en eau des canaux de navigation.

“Climate change affects the poorest in developing countries” As the impact of climate change gains presence in our everyday lives, many countries have engaged in efforts to mitigate the emission of global greenhouse gases (GHGs) in innovative and cost-effective ways to scale up emissions reductions and foster financial flows, including through so-called carbon market instruments. To support, facilitate and build "readiness" for such instruments, the World Bank established a grant-based global partnership of developed and developing countries that provides funding and technical assistance for the collective innovation and piloting of market-based instruments for the reduction of greenhouse gases emissions. This platform, called the Partnership for Market Readiness (PMR), is celebrating its 8th Assembly Meeting in Mexico City, the capital of one of the countries that has established an agenda to prevent and mitigate the effects of climate change as part of its national plan for the next years. 1) What are carbon markets?
