Lessons learned from renewable electricity marketing attempts: a case study

The choice of subscribing to renewable electricity has been available to Australian households for more than a decade, yet consumer uptake remains low for some green marketers. This case study uses a retailer's perspective to examine the implementation of a green marketing program for a renewable electricity retailer. Based on interviews, internal company documentation, and secondary research, findings show that effective differentiation for renewable energy is required to increase consumer involvement levels and the likelihood of consideration. While consumers lack understanding of, and interest in, renewable energy, the marketing program relied on customers to seek information. It was apparent the success of green marketing programs depends on the integration of education into a carefully targeted marketing program emphasizing functional and emotional values to differentiate renewable energy and simplify consumer decision-making processes

Nonlinear conjugate gradient methods in micromagnetics

Conjugate gradient methods for energy minimization in micromagnetics are compared. The comparison of analytic results with numerical simulation shows that standard conjugate gradient method may fail to produce correct results. A method that restricts the step length in the line search is introduced, in order to avoid this problem. When the step length in the line search is controlled, conjugate gradient techniques are a fast and reliable way to compute the hysteresis properties of permanent magnets. The method is applied to investigate demagnetizing effects in NdFe12 based permanent magnets. The reduction of the coercive field by demagnetizing effects is μ0ΔH = 1.4 T at 450 K.© 2017 Author(s
