Renewable energy is generally defined as energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.
Based on REN21's 2014 report, renewables contributed 19 percent to humans' global energy consumption and 22 percent to their generation of electricity in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% is electricity from wind, solar, geothermal, and biomass. Worldwide investments in renewable technologies amounted to more than US$214 billion in 2013, with countries like China and the United States heavily investing in wind, hydro, solar and biofuels.

How much land mass would renewables need to power a nation like the UK? An entire country's worth. In this pragmatic talk, David MacKay tours the basic mathematics that show worrying limitations on our sustainable energy options and explains why we should pursue them anyway. (Filmed at TEDxWarwick.) Lesson by David MacKay.
Is green energy, particularly wind and solar energy, the solution to our climate and energy problems? Or should we be relying on things like natural gas, nuclear energy, and even coal for our energy needs and environmental obligations? Alex Epstein of the Center for Industrial Progress explains.

What comes to mind when we think about renewables? Wind turbines spinning in a field, solar panels on a rooftop. But there’s much more to a cleaner energy future than these images in our mind. Creating a renewables-based energy future will take a lot of time, resources, and commitment. This episode highlights the benefits and challenges facing a renewable energy system and explores how we can achieve it.
The film of the "renewables –Made in Germany" initiative of the Federal Ministry for Economic Affairs and Energy shows the various ways of generating renewable energy and the current related technologies, the comprehensive range of services and the collective expertise of German companies. The main focus is on the transferability of German technologies and the specific ways of applying them. If you are interested in watching the Spanish, French or Arabic version please switch to the correspondent film.
Scottish Renewables believes we should all be proud of the valuable green energy we produce in Scotland. That’s why we decided to create a short animation to present key facts from our 2014 Annual Report, and share the Renewable Story in Scotland so far. Renewables are producing more energy in Scotland than ever before, boosting our economy, helping our environment and providing a multitude of benefits to people across the country. Renewables are delivering for Scotland now, but the future looks even brighter.

The next few decades will herald a global change in energy production. The age of renewables requires more than just photovoltaics and windmills: it needs storage systems in an unprecedented volume. However, conventional techniques of storage fail due to the high investments or the low efficiency. This appears to be a stumbling block for the desired change to renewable energy. His proposed hydraulic hydro storage system gives us a chance to store thousands of GWh at low cost and low environmental impact. The simple yet riveting idea is to lift a rock the size of a soccer stadium using established technologies thereby storing energy. Due to the fact that underground rocks are practically unlimited, the global change to solar power can continue. Please find the slides at http://de.slidesha...

It’s not in the papers but a silent revolution is moving across the world. Renewable energy is becoming cheaper than energy from fossil fuels. It means that progressively the choice for wind and solar energy is no longer an ethical one but an economic one. And this will speed up the transfer to renewable energy.

It's frequently said that variable wind and solar power endanger reliable electricity supply; and so we need either "baseload" fossil fuel-burning power plants, or breakthroughs in bulk storage. That's a myth. Amory Lovins explains why.
Renewable energy sources, including hydropower, now account for around 30% of the total global installed power generating capacity, and 23% of total global electricity production. Renewables have undoubtedly become big business, reaching a record $286 Billion investment in new renewables capacity in 2015. However, the increasing share of intermittent renewables still presents a number of challenges. Generally, an energy system that lacks effective market signals to deliver back-up capacity or storage to effectively integrate the increasing share of intermittent renewables and a lack of transmission planning has repeatedly lead to regional bottlenecks or to the idling of new renewable capacity.

The late IAFOR Chairman, Professor Stuart D. B. Picken, interviews Colin Donald, Business Editor of the Sunday Herald. Mr Donald gave a very insightful presentation, entitled "Green Tartan – The Scottish Renewables Challenge", on the various issues Scotland is addressing in the building of a renewable energies infrastructure. Mr Donald explains how he became interested in this topic and what drove him to expand his investigation of the European renewables market, and he and Professor Picken discuss the possible motivations and political agendas behind the decisions carried out by government policy makers. They go into detail about the circumstances involved in Scotland's development of a renewables infrastructure and whether the creation of such an infrastructure could generate the income...
Renewables 10th October 2016
WHEN an entire state went dark last week, rightly or wrongly, people started questioning whether renewables were reliable.The huge storm that swept through South Australia produced a tornado and brought down 23 transmission towers eventually leading to the blackout last week.While it’s been acknowledged that the one-in-50-year storm was the main reason the lights went out, it’s led to questions about whether the state’s reliance on wind farms made any difference to whether the blackout would have occurred.A preliminary report from Australian Energy Market Operator released this week seemed to raise more questions as it found there was a drop in electricity being generated from six wind farms in the seconds before the blackout.

Electricity is a vital form of energy, which is essential for everyday life. At the same time, 40% of energy-related CO2 emissions come from electricity generation, which is one of the factors behind the increase in renewable generation. Electricity will play and ever more important role in the future, but their measurement can be challenging with more distributed connections. This webinar will provide participants the opportunity to understand basic concepts of statistics for electricity and renewables, convey production and transformation for fuel use.
Renewables are defining the energy future for India. Wind, sun, biomass and water are fuelling this drive. India is moving ahead step by step. Spanning across the states of Uttaranchal, Maharashtra, Gujarat, West Bengal, Karnataka and Kerala, Renewing India takes you through some of the milestones in India's journey on the path of alternatives. This film is divided in five short segments- each highlighting hydropower, solar photovoltaic, solar thermal, wind energy and biomass. The film brings out how renewable energy has been a catalyst of change for many people living in rural India who had no access to modern energy. It also documents how renewables in India have sparkled in every sphere-be it technology, innovations or market.
Meeting # 3,275 - College regular Tim Bolger will present evidence and arguments on: "Why renewable energy like wind and solar will not cut our demand for fossil fuels nor will it be the "whole" solution, to why we need more than just renewables." With a solution presented about thorium nuclear power.
This course deals with the integration of renewable energies into the existing power system. It starts with the general context, i.e. different types of renewable energies, their increasing pen-etration in recent years and the voltage levels at which they are connected. Furthermore, the fundamentals encompass the prevalent generation and load management, both for covering the electricity demand and for providing ancillary services. Subsequently, this course takes a more profound look at the potential of renewable energies to substitute conventional genera-tion at the provision of energy and ancillary services in the future.
You are not an enemy anymore
