China`s Overseas Investments in the Wind and Solar Industries: Trends and Drivers
Shifting to a low-carbon economy will require current emitting countries and projected future emitters to rapidly scale up their investments in renewable energy. In recent years, major emerging economies like China, India, and Brazil have been catching up with leading developed country investors in Europe and the United States. By some estimates, China is already the leading global investor in ...

Renewable Energy Market in Indonesia
The development of renewable energy in Indonesia has stalled in recent years, especially wind and solar PV power. By the end of 2018, cumulative installed solar and wind capacity in Indonesia just reached 136MW, which is at a relatively low level compared with other Southeast Asian countries. It is a recognized fact that 2019 was the year of Vietnam’s renewable energy explosion, with a new ...

A hybrid wind/solar/diesel stand alone system optimisation for remote areas in Algeria
While Algeria has an important potential of wind and solar energies, their share in the primary energy supply is relatively low compared to the fossil energy. In this paper, we propose to carry out a techno–economical study of a hybrid stand alone system in order to draw the attention to the feasibility of such systems. For this purpose, sites of Hassi–R'mel and Adrar have been ...

How renewable energy advocates are hurting the climate cause
Overly optimistic reports of renewables’ success are not only misleading but also counterproductive In the wake of the 2016 presidential election, the proliferation of misinformation on social media is finally getting the attention it deserves. Or so I thought. Scrolling through my Facebook news feed recently, I stumbled upon an article shared by Climate Central, a nonprofit news ...

Size optimisation of hybrid wind-PV power generation systems for remote rural areas
Electrical power generation with renewable energies, such as wind and solar, plays an important role in the electrification of remote rural areas. Since there are always seasonal and synoptic variations in wind and solar resources, a hybrid system, consisting of both wind and solar energy, may be more reliable and economical than a single energy system: this is because either energy can ...

China invests billions in international renewable energy projects
It’s well-known that China ranks first in the world in attracting clean energy investment, receiving US$ 65.1 billion in 2012. But new analysis from WRI shows another side to this story: China is increasingly becoming a global force in international clean energy investment, too. In fact, the country has provided nearly $40 billion dollars to other countries’ solar and wind industries ...

Energetic and exergetic assessment of solar and wind potentials in Europe
This paper deals with a physics–based assessment of renewable energy potential in Europe, particularly solar and wind energy sources, using two literature models. A sensibility analysis with the weather data is first done. Actual temperature, pressure, relative humidity, global radiation and wind speed data are employed to develop energy and exergy maps for Europe, based on iso–areas of land–use. ...

Development and opportunities of distributed generation fuelled by renewable energy sources
The key issue to the widespread of distributed generation (DG) is the ability to safely, reliably and economically interconnect new energy sources with the existing distribution network 'utility grid'. With the rising prices of petroleum fuel sources, a high expected penetration of renewable energy sources (RES) such as wind and solar as part of the emerging DG fuel resource are expected to be ...

Optimizing Wind and Solar Power in Africa
Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...

Structure-preserving dynamical model and distributed stabilisation of electricity infrastructures with renewable energy resources
This paper introduces a module-based approach to modelling and controlling electricity infrastructure with a high penetration of distributed renewable energy resources. Each energy-converting component is defined as a module and is represented in terms of its local variables and the interaction variables between the module and the transmission network. The structure of the electricity ...

Next-Gen Battery Storage
A utility in Oregon recently announced the largest wind-solar-storage project in the U.S that will generate nearly 380 MW of energy. This is a good example of how utilities are storing energy from intermittent sources (like wind or solar) in grid-scale batteries. Grid-scale batteries are the perfect match to wind and solar installations, storing energy during peak production and releasing power ...

Renewable energy technologies and the European industry
The European renewable energy industry has the potential to be a world leader. This has been achieved within the European region for specific technologies, through a set of policy activities at a national and regional level, driven primarily by employment, energy self-sufficiency and industrial competitiveness. Using the experience gained in recent years, European industry has the opportunity to ...

Optimal scheduling and operation of hybrid biomass/wind/PV energy system for rural areas
In this paper, a hybrid energy system consisting of biomass, wind, solar photovoltaic (SPV) and battery, is proposed. The sources are operated to deliver energy at optimum efficiency. An optimisation model is developed to supply the available energy to the loads according to the priority. It is also proposed to maintain a fair level of energy storage to meet the peak load demand together with ...

New national lab reports: Rapid growth expected for grid-scale U.S. storage capacity
Energy storage has rapidly evolved from a niche application just a few years ago into an increasingly cost competitive and fast-growing technology that complements wind and solar. And two new national lab reports find storage growth is poised to explode. Grid-scale U.S. energy storage capacity could increase five-fold by 2050 according to the latest report from NREL’s Storage Futures Study ...
