You are what you measure! But are we measuring it right? An empiric analysis of energy access metrics based on a multi-tier approach in Bangladesh
Measuring energy access through binary indicators is
insufficient, and often, even misleading. In this work, the
SE4ALL global tracking framework, and the recently
introduced ESMAP multi-tier approach, is critically
discussed analyzing questionnaire based primary data from
rural Bangladesh. The performance of different energy
interventions is evaluated using the new tier framework.
The challenges in its application lie in reliable data
collection, adequate gradation of indicators, and an
effective algorithm for the tier assignment based on the
specified set of attributes. The study showcases very high
sensitivities to parameter changes, different algorithms, and data requirements. The results reveal a clear trade-off
between capturing the multi-dimensionality of energy
access and the simplicity of an easy to use global
framework. Suggestions to improve the measuring
approach are made and conclusions are drawn for possible
implications of the tier framework for different energy
service offers in the market. Strengths and weaknesses of
the present measurement scheme are discussed and country
specific results interpreted through targeted gap analysis for future policy advice
Application of Wireless Nano Sensors Network and Nanotechnology in Precision Agriculture: Review
Due to a series of global issues in recent years, such as the food crisis, the impact of fertilizer on climate change, and improper use of irrigation that’s way precision agriculture is the best solution for alleviating this problem. One of the most important and interesting information technology is the wireless Nanosensor network with the help of Nanotechnology will boost crop productivity, maintain the fertility status of the soil, save the water with precise application of irrigation in the field and minimize the loss of excess fertilizer through the precise application. In this paper, we have surveyed the importance of sensor networks in precision agriculture and the importance of Nanosensors with the help of Nanotechnology for remote monitoring in the various application of the agriculture field.

Energy Efficiency in Buildings: Both New and Rehabilitated
Buildings are one of the main causes of the emission of greenhouse gases in the world. Europe alone is responsible for more than 30% of emissions, or about 900 million tons of CO2 per year. Heating and air conditioning are the main cause of greenhouse gas emissions in buildings. Most buildings currently in use were built with poor energy efficiency criteria or, depending on the country and the date of construction, none at all. Therefore, regardless of whether construction regulations are becoming stricter, the real challenge nowadays is the energy rehabilitation of existing buildings. It is currently a priority to reduce (or, ideally, eliminate) the waste of energy in buildings and, at the same time, supply the necessary energy through renewable sources. The first can be achieved by improving the architectural design, construction methods, and materials used, as well as the efficiency of the facilities and systems; the second can be achieved through the integration of renewable energy (wind, solar, geothermal, etc.) in buildings. In any case, regardless of whether the energy used is renewable or not, the efficiency must always be taken into account. The most profitable and clean energy is that which is not consumed
Solar Energy: A Fresh Look at the Sun
This paper was my attempt to give solar energy a voice in the midst of discussion about the growing problems with global warming, fossil fuels, and bio-fuels. In reading and studying these topics, it becomes clear that with or without considering the damage fossil fuels are doing to the planet, there are many economic and political reasons to seriously consider alternative sources of energy. However, switching to new sources should be done with careful consideration of their own pros and cons. In my reading about solar energy, the pros seemed undeniable and the cons seemed surmountable. Solar energy has not received the same level of hype or government support that fossil and bio-fuels have enjoyed. The public seems to know little about solar energy – how it works, its benefits, the misconceptions about its pitfalls, and its capabilities. Fortunately, other countries such as Japan and Germany have already taken the initiative to test out policies to support solar energy and have had great results. Unfortunately, the U.S. does not seem to be moving in the same direction. This paper was written with the intent to spread the idea of free, truly green energy, not just for the future, but for the present as well
Efficiency and Sustainability of the Distributed Renewable Hybrid Power Systems Based on the Energy Internet, Blockchain Technology and Smart Contracts
The climate changes that are visible today are a challenge for the global research community. In this context, renewable energy sources, fuel cell systems, and other energy generating sources must be optimally combined and connected to the grid system using advanced energy transaction methods. As this book presents the latest solutions in the implementation of fuel cell and renewable energy in mobile and stationary applications such as hybrid and microgrid power systems based on energy internet, blockchain technology, and smart contracts, we hope that they are of interest to readers working in the related fields mentioned above
Energy Efficiency
Energy efficiency is finally a common sense term. Nowadays almost everyone knows that using energy more efficiently saves money, reduces the emissions of greenhouse gasses and lowers dependence on imported fossil fuels. We are living in a fossil age at the peak of its strength. Competition for securing resources for fuelling economic development is increasing, price of fuels will increase while availability of would gradually decline. Small nations will be first to suffer if caught unprepared in the midst of the struggle for resources among the large players. Here it is where energy efficiency has a potential to lead toward the natural next step - transition away from imported fossil fuels! Someone said that the only thing more harmful then fossil fuel is fossilized thinking. It is our sincere hope that some of chapters in this book will influence you to take a fresh look at the transition to low carbon economy and the role that energy efficiency can play in that process
