Pumped-storage hydropower from Norwegian water reservoirs can secure Europe’s power supply in the future. A regulated power reserve is required when the wind isn’t blowing and wind turbines aren’t producing energy. Read more here: http://statkraft.com/energy-sources/hydropower/pumped-storage-hydropower/

Is Geothermal Heating & Cooling Worth It? It’s been 4 years since I installed my DIY Geothermal System, and with some experience with it, I can firmly say it was worth every penny. It may not be the perfect system for every application, but it is perfect for mine. My average monthly electric bill is only 0 per month for a 6000 square foot house. I think that speaks volumes itself.

7 Types Of Renewable Energy
Solar
Solar energy is derived by capturing radiant energy from sunlight and converting it into heat, electricity, or hot water.
With the technology to harvest it, there is a limitless supply of solar energy, meaning it could render fossil fuels obsolete.
Wind
Wind farms capture the energy of wind flow by using turbines and converting it into electricity.
Wind energy is a clean energy source, which means that it doesn’t pollute the air like other forms of energy.
Wind energy doesn’t produce carbon dioxide, or release any harmful products that can cause environmental degradation or negatively affect human health like smog, acid rain, or other heat-trapping gases.
Hydroelectric
Water flows through the dam’s turbines to produce electricity, known as pumped-storage hydropower.
Hydroelectric power is very versatile and can be generated using both large scale projects, like the Hoover Dam, and small scale projects like underwater turbines and lower dams on small rivers and streams.
Geothermal
Geothermal heat is heat that is trapped beneath the earth’s crust from the formation of the Earth 4.5 billion years ago and from radioactive decay.
Geothermal energy is not as common as other types of renewable energy sources, but it has a significant potential for energy supply.
Geothermal energy is naturally replenished and therefore does not run a risk of depleting (on a human timescale).
Ocean
The ocean can produce two types of energy: thermal and mechanical.
Ocean thermal energy relies on warm water surface temperatures to generate energy through a variety of different systems.
Ocean mechanical energy uses the ebbs and flows of the tides to generate energy, which is created by the earth’s rotation and gravity from the moon.
Unlike other forms of renewable energy, wave energy is predictable and it’s easy to estimate the amount of energy that will be produced.
This type of renewable energy is also abundant, the most populated cities tend to be near oceans and harbors, making it easier to harness this energy for the local population.
Hydrogen
Hydrogen needs to be combined with other elements, such as oxygen to make water as it does not occur naturally as a gas on its own.
When hydrogen is separated from another element it can be used for both fuel and electricity.
Hydrogen can be used as a clean burning fuel, which leads to less pollution and a cleaner environment.
It can also be used for fuel cells which are similar to batteries and can be used for powering an electric motor.
Biomass
Bioenergy is a renewable energy derived from biomass.
Biomass is organic matter that comes from recently living plants and organisms.
The use of biomass in energy production creates carbon dioxide that is put into the air, but the regeneration of plants consumes the same amount of carbon dioxide, which is said to create a balanced atmosphere.
Biomass can be used in a number of different ways in our daily lives, not only for personal use, but businesses as well.

The oceans, that cover most of the planet, are full of energy. So much, in fact, that if we could harness that of all the waves, we’d fulfill global demand three times over. There’s just one small problem: No one has figured out exactly how to make this work long-term. But we could be on the cusp of sea change.

We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our channel explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.

This video sheds light on where biomass used for bioenergy comes from. The industry makes use of residue and wood that cannot be used in other sectors as a source of energy.
As part of sustainable forest management, bioenergy provides energy, rural development, GHG emission reductions and increased forest resilience.

BECCS, or Bio-Energy with Carbon Capture and Storage, is a technology that the IPCC has factored into their climate modelling. If it is to have the effect of keeping their models to well below 2 degrees Celsius of warming compared to pre-industrial levels then it will need to be implemented on a vast scale around the globe.
This week we take a snapshot of scientific and journalistic analysis of this controversial proposal.

Offshore wind farms solve one of renewable energy’s biggest problems: unreliability. With wind almost always blowing on sea, there is no lack of power. But the technology is struggling with a bunch of other hurdles.
