The provision of adequate, reliable, and affordable energy, in conformity with social and environmental requirements is a vital part of sustainable development. Currently, countries are facing a two-fold energy challenge: on the one hand they should assure the provision of environmentally sustainable energy, while, on the other, energy services should be reliable, affordable, and socially acceptable. To evaluate such aspects of energy services one needs energy sustainability barometers, which provide the means to monitor the impacts of energy policies and assist policymakers in relevant decision making. Although sustainability is an ambiguous, complex, and polymorphous concept, all energy sustainability barometers incorporate the three major sustainability dimensions: social, economic, and environmental. In this chapter, we review three models for assessing the sustainability of energy development of countries: ESI, SAFE, and EAPI. We also present a brief discussion of the results, the applied methodologies, and the underlying assumptions of these sustainability barometers.

The growing world-wide energy demand and environmental considerations have attracted immense attention in building energy efficiency. Climate zone plays a major role in the process of decision making for energy efficiency projects. In the present paper, an office building located in Melbourne, FL is considered. The building is built in 1961 and the goal is to identify and prioritize the potential energy saving opportunities and retrofit the existing building into a Net-Zero Energy Building (NZEB). An energy assessment is performed and a baseline model is developed using eQUEST to simulate the energy performance of the building. Several possible energy efficiency improvement scenarios are considered and assessed through simulation including improving insulation on the walls and roof, replacing HVAC units and upgrade their control strategies, use of high efficiency lighting, and more. Selected energy efficiency improvement recommendations are implemented on the building model to achieve the lowest energy consumption. It is considered that photovoltaic (PV) panels will be used to supply the energy demand of the building. Simulations are also performed to determine the number of required PV panels and associated cost of the system is estimated. The results from this paper can help with the decision making regarding retrofit projects for NZEB in humid subtropical climate.

My purpose in this paper is threefold. First, I would like to examine why the world needs us to produce more energy. Second, I will look at the range of energy sources available for a sustainable future. A number of myths have grown up around the various energy sources and their relative contribution to addressing the global energy challenge: I will seek to dispel some of those. Third, I want to highlight what I see as an urgent need: for more informed decision making and more action in this complex area.
